Is it possible to edit the microsoft equation object. Creating and Inserting a Formula in Word - Step-by-Step Guide

The need to have a means for entering mathematical expressions into a text document is typical for scientific and technical documentation. One of these tools in the program Microsoft Word is a formula editor. It allows you to create formula objects and insert them into a text document. The simplest formulas in Microsoft Word can be created using various character format attributes ( superscript, subscript etc.), as well as a symbol table, to call which you should specify Insert/Symbols/Symbol. In the window that opens Symbol need to choose a font Symbol, which contains Greek letters and some mathematical symbols that cannot be entered from the keyboard.

Create formulas in Microsoft editor Equation 3.0

On the tab Insert click the button An object.

In the dialog box that opens Inserting an object you should select the tab " Creation", in the list that opens " Object type" choose Microsoft Equation 3.0.

The control panel opens Formula(Fig. 1). This replaces the Word word processor menu bar with the menu bar Formula editor . And at the cursor position a frame appears, limiting the area of ​​the formula being created (its size will change as the formula is entered).

Creating formulas is done by entering numbers and letters representing variables in the space marked by the vertical cursor bar and by using the buttons on the Formula Editor control panel.

When entering formulas, you can move the cursor using the cursor keys or the mouse.

When creating formulas, only the last action performed is undone ( Edit/Cancel).

When entering formulas, you can copy and paste repeating parts of the formula ( Edit/Copy And Edit/Paste).

Entering and editing formulas is completed by pressing the key Esc or by left-clicking anywhere in a document field outside the formula entry area. The entered formula is automatically inserted into the text as an object. Then it can be moved to any other place in the document via the clipboard ( Ctrl+X- cut out; Ctrl+V- insert).

Setting up the formula editor

The setup consists of assigning fonts for various elements included in the formulas. This is done in the dialog box Styles opened by the command Style/Define.

Other (optional) settings of the formula editor are made in the dialog box Interval opened by the command Format/Spacing. The numerous adjustment tools present in it are designed to set the sizes of various elements of various elements of the formulas.

Types of buttons on the formula editor toolbar

The formula editor toolbar contains two rows of buttons (Fig. 1).

Rice. 1. Formula editor control panel

On top panel(mathematical symbols) there are buttons for inserting more than 150 mathematical symbols into the formula, most of which are not available in standard font Symbol. To insert symbols into a formula, click the button in the top row of the toolbar, and then select a specific symbol from the palette that appears above the button.

The buttons on the bottom panel (templates) are designed to insert templates or structures that include symbols such as fractions, radicals, sums, integrals, products, matrices and various parentheses or corresponding pairs of symbols such as round and square brackets. Many templates contain special places where you can enter text and insert symbols. The formula editor contains about 120 templates grouped into palettes. Templates can be nested one inside another to build multi-step formulas.

Many users experience difficulties when they need to insert formulas in Word, because text editor From Microsoft this feature is rather unobvious.

The situation is complicated by the fact that one of the most popular word processing programs in the world is completely updated every few years.

As a result, the interface is redesigned and the controls change their location.

Therefore, if you knew Word 2003 perfectly, then when working with newer versions you may have questions about how to do this or that action that you previously performed automatically.

This statement is completely true for inserting formulas.

Working with formulas in Word 2003

This version of the text editor was the last to create documents in the well-known DOC format by default (supported since 1997), and the first to undergo a commercial rebranding from MS.

As the future has shown, a change in design Office package 2007 became very effective solution, as evidenced by the fact that many organizations and private users still use the package office programs exactly this version.

A specific feature of Word 2003 is the use of a separate Microsoft applications Equations 0.3 for working with formulas, the window of which opens every time you insert a new mathematical expression.

• To insert a formula, you need to find the “Insert” item in the top panel and select “Object” from the drop-down menu.

• After this, a window for selecting an insertion object will appear. You must click on Microsoft Equations 3.0

• After this, the formula editor will automatically launch and the main window of this subroutine will open in front of the user, in which you can write any possible formula construction.

• The program has a laconic interface, made in accordance with the design style of all Microsoft products of that period. At the top there is a control panel on which there are standard features.
  Below are categories of various mathematical symbols, after selecting one of which a list of available elements will open. In order to select the desired symbol, just click on it with the left mouse button.
  All the notation is intuitive, many of them have a dotted rectangle icon indicating that there should be some kind of mathematical expression in that place.

• The style function allows you to select the font and style type for certain characters. To ask own settings, click Style and then Define.

• The “Size” menu item makes it possible to adjust the size of various formula elements and also has the ability to set custom settings, for which you need to follow the path “Size” - “Define”.

Advice! You cannot put a space in the formula editor - the sizes between elements are adjusted automatically. If you need to insert an interval of a particular length, select the appropriate element from the suggested characters.

• When you have completed entering the formula, press Esc or close the window, as a result of which it will be inserted into the main element. Repeated editing is carried out by double-clicking LMB.
  The size of the formula field can be changed and moved by simply dragging the mouse.

Working with formulas in Word 2007 and 2010

Word 2010 and Word 2007 are very similar to each other, which also applies to the formula editor.

Therefore, if you are using a Microsoft office suite released in 2010, you can use the instructions described above to insert mathematical expressions.

This version of the text editor has its own formula designer, which has its own taskbar. Therefore, working with it is significantly different from Word 2003.

• To create a formula, use the “Insert” item and the “Formula” subitem, after activating which the user is offered the most common options, such as Newton’s binomial, area of ​​a circle, etc.
  To enter your own expression, select the “Insert new formula” function.

• As a result of these actions, the constructor for working with formulas will be opened, having own panel tools, divided into three categories: Service, Symbols and Structures.
  Despite a large number of capabilities, there is no numbering, but even during the first acquaintance this is not a big problem.

• The functions of the Service category allow you to select any standard expression, and if you click on the small arrow at the bottom of the panel, the formula parameters window will open, in which you can set some specific settings, before inserting a custom formula, but most of them to the average user are unlikely to be useful.

• The next category is the most important, as it gives access to all possible symbols. By default, the table displays basic mathematical symbols such as operation signs, infinity symbol, equals symbol, etc.
  To insert, for example, a Greek letter, you need to change the group of symbols, for which LMB click on the arrow below the scroll slider, and then on the triangle after the name of the symbol group and select the required selection.

• The last category of functions provides the user with various standard symbol constructions such as fraction, limit, trigonometric functions, with the help of which mathematical calculations are carried out.
  Everything here is intuitive: select the appropriate subcategory, click on it, and then click on the specific expression.

• The finished formula does not require saving, since it is one of the insertion elements, along with clips, pictures or diagrams. To continue working on other elements, just move the cursor to another part of the document and continue writing text.
  To change the formula, click on it once. The formula can be dragged by “grabbing” the panel to the left of the input field, which shows three dots.

Today, almost all people use Microsoft Word. This is especially true for office employees. In addition, this text editor is especially popular among students and schoolchildren, since they often have to write various coursework and independent work. But not everyone knows how to insert a formula in Word.

This article will discuss the basic principles and capabilities of working with equations. In addition, differences in different versions editor. If you are still using Word 2007, read these instructions, you will understand that it is high time to upgrade.

In order to insert any equation, you need to do the following:

1. Click on the “Tab” menu item. Click on the down arrow icon. Thanks to this, there will be more menu items.

1. Then select the “Object” item.

1. In the window that appears, select “Microsoft Equation 3.0”. To insert, click on the “OK” button.

1. When you launch the editor for the first time, Windows will configure it. You must wait for the process to complete.

1. After this, you will be able to create various formulas.

1. To do this, you first need to click in the selected area, and then select a section of formulas and the appropriate option.

1. Immediately after this, the selected element will appear in the formula input field. Here you can write whatever you want.

1. Enter some number. To exit the editor, you need to left-click on the empty space.

1. Thanks to these actions, the element will no longer be active and you will see the finished equation.

This editor has been preserved in subsequent versions of Word. You can read more about its capabilities in the online help on the official Microsoft website.

MS Word 2007, 2010

This release of the office suite was revolutionary for Microsoft. His appearance has improved significantly. In addition, it appeared great amount new features and functions.

Word 2007 has new editor formulas that are many times superior to Microsoft Equation 3.0. But you can’t abandon the old one either, since document support will be lost Word format 2003.

Ready options

One of the main innovations is a pre-prepared set of various mathematical equations. To see this list, you need to do the following:

1. Open the "Insert" section. Click on the triangle next to the “Formula” button. After this it will appear big list popular expressions:
   • binomial theorem;
   • quadratic equation;
   • area of ​​a circle;
   • decomposition of the sum;
   • Taylor series;
   • Fourier series;
   • Pythagorean theorem;
   • various trigonometric identities.

1. After you select one of the proposed options, you will have new inset“Constructor”, where you can edit any equation.

Inserting a new formula

In order to insert something of your own, rather than using a blank, you need to take the following steps:

1. Click on empty place(or wherever you need to insert the equation).
2. Open the Insert tab.
3. Click on the "Formula" button.

1. Immediately after this, “Space to enter” will appear. Here you can write something by hand.

1. In addition, you can insert some kind of structure.

The principle of operation in modern editors is almost the same as in Word 2007 and 2010. Of course, a number of changes have occurred. But the concept remains the same. Therefore more detailed review various features will be carried out on modern versions.

Working with formulas in MS Word 2013, 2016

The first thing you should pay attention to is the change in the name of the function. Now it's called "Equations".

Built-in equations

In order to see template options, you need to do the following:

1. Go to the "Insert" tab.
2. Click on the “Symbols” button.
3. Click on the triangle icon next to the “Equation” item.
4. Select any desired option.

The developers from Microsoft tried their best and made a selection of the most relevant expressions.

More equations from Office.com

But if this is not enough for you, then you can open the extended list. To do this, you need to repeat the steps described above, but instead of selecting a formula, click on the item of the same name below.

As a result, you will see the following list:

• absolute value;
• reproduction of fractions to powers;
• reproduction of degree to degree;
• the second law of actions with exponents;
• fractional exponents;
• negative exponent.

Insert new equation

If the options suggested above are not enough, you can always create something of your own. For example, the sum of squares or something else. To do this you need to do the following:

1. Go to the "Insert" tab.
2. Click on the "Symbols" button.
3. Click on the "Equation" icon.

1. This will result in "Equation Space". In addition, the toolbar will automatically switch to the Design tab.

If you have a small monitor resolution or the Microsoft Word application window is not full screen, then the panel will take the following form. All elements will still be available, but you will have to make an extra click to get to them.

Formula structures

Thanks to these constructions, you can create equations of any complexity, since all known mathematical operators can be found there. For example, you can even build a matrix table.

Let's take a closer look at the structures. These include:

• fraction;

• index;

• radical (roots);

• integrals:
  • ordinary;
  • contour;
  • differentials.

• major operator:
  • amounts;
  • works;
  • unions and intersections;
  • other large operators;
  • ordinary large operators.

• bracket:
  • standard view;
  • brackets and separators;
  • separate brackets.

• condition sets and brackets;
• regular parentheses.

• function;
  • trigonometric;
  • reverse;
  • hyperbolic;
  • inverse hyperbolic;
  • basic.

• diacritics:
  • ordinary;
  • formulas within;
  • features above and below;
  • objects with regular diacritics.

• limit and logarithm:
  • functions;
  • main functions.

• operator:
  • basic;
  • structures;
  • basic structures.

• matrix:
  • empty;
  • dots;
  • single;
  • matrices with brackets;
  • sparse matrices.

As you can see, thanks to this you will be able to create mathematical expressions and physical formulas of any complexity.

Using symbols in a constructor

In order to expand the capabilities, a “Symbols” section has been added to the “Design” tab. For example, a parenthesis, a hash mark, a greater than sign, a number, and so on - you can easily type using the keyboard. But the rest will be a problem.

In order to expand the list completely, you need to click on the triangle in the lower right corner of this block.

As a result of this, you will see the following list.

Character categories

Notice that there is a drop-down list at the top. If you click on it, you can see a list of all available categories. The default is "Basic Math Symbols".

Other sets include:

• Greek letters;

• letter-like characters;

• operators;

• arrows;

• relationships with denial;

• special letter styles;

• geometry.

Inserting regular characters

In addition, it is possible to use standard characters, which are intended for plain text. To do this you need to do the following:

1. Open the "Insert" tab.
2. Click on the “Symbols” icon.
3. Then select the “Symbol” option.
4. A list of recently used items will then appear. To insert, just click on any of them.

1. In order to expand the entire list, you need to click on the “Other symbols” item.

1. As a result of this, you will see the following window.

1. Here you can also change the content depending on the set. And there are a lot of them - the list is quite impressive.

On this tab you can see additional list symbols and corresponding keyboard shortcuts.

Assigning a new keyboard shortcut

If a certain character needs to be inserted very often, then you can always create your own combination of buttons on the keyboard. This method is much faster than numerous menu clicks.

To do this you need to take the following steps:

1. Select the desired item from the list.
2. Next, you need to click on the “Keyboard shortcut” button.

1. This will open the “Keyboard Settings” window. Click on the “New keyboard shortcut” field.
2. Press the desired combination of keys on your keyboard.
3. After this, the “Assign” button will become active. To save the settings, click on it.

In addition, you can use the autocorrect function. To do this, click on the appropriate button.

In the window that opens, go to the “AutoCorrect with Mathematical Symbols” tab. Thanks to this, you will see a large list of different combinations.

If you enter regular text into the equation field, it will appear in italics. The editor has a large set of functions that are reserved and not highlighted because they are formulas.

If you want to add something non-standard, you need to click on the “Recognized functions” button.

Then in the window that appears, enter what you want and click on the “Add” button. To save, click on “OK”.

As a visual aid, let's try to create a formula for the period of oscillation of a mathematical pendulum. It looks like this.

To do this, you must perform the following steps.

1. Go to the “Insert” tab. Click on the “Symbols” button. Click on the “Equation” item.

1. This will result in "Equation Space".

1. Enter the leading characters "T=2". Then, in the list of symbols, click on the “π” icon (how to do this was described a little higher).

1. Then add the root. To do this, click on the “Radical” icon and select the most common option.

1. In the element that appears, click on the square, which is an input field.

1. After this, insert the usual vertical fraction.

1. In the fraction that appears, we enter the letters we need into each square one by one. Then simply click in an empty area of ​​the document.

1. As a result of this, you will see a ready-made physical formula.

Saving formulas

If you use an expression very often, then instead of entering it again each time, it is best to save it and use a ready-made template in the future.

This is done very easily.

1. Right click on empty space in the formula. It is in the workspace of this object, and not on the page. This space is highlighted in grey.
2. Then, from the context menu that appears, select “Save as New Equation.”

1. As a result, the “Create a new building block” window will appear.
2. Here you can specify:
   • collection;
   • category;
   • a description that you would like to specify (this field is empty by default, unlike all the others).
3. To save, click on the “OK” button.

You can see the result of your efforts as follows.

1. Open the “Insert” tab.
2. Then click on the “Symbols” button.
3. Click on the triangle under the “Equation” icon.
4. After this, a large list of standard equations will appear.
5. By scrolling to the very bottom, you will see that new category"Are common". This is where all your saved formula options will be located.

For those who do not want to make a lot of clicks on different designs and symbols, Microsoft developers have come up with an option manual entry formulas To do this, open the “Design” tab and click on the corresponding button.

As a result, the following window will appear.

Here, in addition to preview and drawing fields, you can see additional buttons:

• write down;
• erase;
• select and correct;
• clear.

Try to draw something and it will automatically transform into a beautiful expression.

Try to draw the symbols as neatly and clearly as possible. The editor is very smart, but he is not a psychic. It is impossible to make out unclear handwriting.

After you see the desired result, you will need to click on the “Insert” button.

Decor

As a rule, almost all objects can be edited in the Microsoft Word editor. And equations are no exception.

Appearance

By default, all formulas have a professional look. But this can be changed.

1. To do this, you first need to right-click on an empty area in the equation.
2. Then select “Linear” from the context menu that appears.

1. As a result of this you will see the following.

Sometimes it is necessary to highlight an equation to differentiate it from the main text. To do this, just increase the size of the characters by a few points.

In addition, you can (for convenience, keyboard shortcuts to call this function are indicated in parentheses):

• select font (Ctrl +Shift +F);
• indicate right size(Ctrl +Shift +P);
• decrease by a few points (Ctrl +[ );
• change text color;
• add various effects;
• make some characters bold (Ctrl +B), italic (Ctrl +I) or underlined (Ctrl +U).

By default, they all have a vertical view. But this can be fixed.

1. Right-click on the fraction.
2. In the context menu that appears, you can select any of the options offered to you.

These include:

• diagonal fraction;

• horizontal option;

Working with degrees (indices)

If you click on the main square of the corresponding element, the following options will appear in the context menu.

If you right-click on the secondary squares, the menu will change.

When working with roots, the context menu takes the following form. For example, you can add a box to indicate the degree.

The result will be as follows.

Generalization

It is important to understand that this way you can work with any element of the formula. Wherever you right-click the mouse, the corresponding context menu will always appear. Its contents will depend on where exactly you clicked.

Thanks to this, you can change the appearance of equations beyond recognition, compared to the default options. But don't overdo it. Try to adhere to generally accepted norms.

Conclusion

Microsoft Word editor is very powerful tool for creating and working with various equations of any complexity. This article covered all the basic possibilities of working with formulas. If things don't work out for you, you're probably clicking on the wrong things.

Video instruction

For those who still have any questions, a video with additional comments on the instructions described above is attached below.

It's hard to imagine a diploma or coursework no formulas. In works on the exact sciences (mathematics, physics, chemistry) you simply cannot do without them; economists often use formulas in their research, and sometimes linguistic specialists cannot do without calculations. Therefore, the story about the rules for preparing coursework and theses would not be complete without information on how to correctly type and place the formula in the text.

The Word text editor provides all the options for inserting formulas. There is a special tool for working with them - the formula editor. With it you can create complex formulas, selecting symbols from the toolbar and defining variables and numbers. In this case, font sizes, spacing and formats are automatically adjusted in accordance with the rules for writing mathematical expressions.

Note

Editor Word formulas is special version MathType equation editor developed by Design Science, Inc., customized for use with Microsoft products.

Before you start working with formulas, determine whether you have the formula editor installed. You can do this by trying to paste the formula into the document. To do this, select Insert > Object, then on the Create tab, select Microsoft Equation 3.0 and click OK. If the component is installed, a field for entering a formula and a toolbar for selecting formula templates will appear in the document window. In addition, the appearance of the main menu will change Word editor. If the component has not been installed before, you will be prompted to do so now.

Note

To make it easier to call the formula editor, place its button on the toolbar. You can do this by going to View > Toolbars > Customize. On the Commands tab, select Insert on the left side of the window, and on the right, find the Formula Editor icon and drag it to any toolbar.

Entering formulas

To enter formulas, there is a special Microsoft Equation toolbar, which is displayed in the Word window after launching the formula editor. The operating principle is as follows: if you need to enter simple formula, something like x + 4, you can just type it on your keyboard. For more difficult situations, for example, when using square roots, powers, integrals, you should refer to the toolbar. Her top part intended for selection special characters. It contains more than 150 mathematical symbols, most of which are not available in the standard Symbol font (Figure 3.1).

Rice. 3.1. Word Formula Editor Toolbar

Here are the letters of the Greek alphabet, as well as special mathematical symbols: the infinity symbol, set theory symbols, logical symbols and comparison signs. Homogeneous symbols are collected into unique groups - palettes. When you select a symbol from the palette, it is inserted into the formula in the same way as when entered from the keyboard.

At the bottom of the formula editor panel there are templates designed for constructing formulas - fractions, integrals, sums and other complex expressions.

A formula template is a ready-made formatted set of characters and empty fields for entering them. The formula editor has about 120 templates, also grouped into palettes.

Before entering the formula, you must select required template, and then click on the appropriate fields to type the mathematical expression. For example, you need to enter the symbol x, and then select the superscript template and enter the number 7. When entering formulas using templates, you can use the symbols in the top row of the formula editor toolbar (Fig. 3.2).

Rice. 3.2. Entering formulas using templates located on the toolbar

Note

If necessary, you can use nested templates when entering formulas. In this case, they must be selected sequentially: first, the main one is for the fraction, and then, by placing the cursor in the appropriate fields, additional ones, for example, the degree and root templates.

The cursor position when working with formulas has great importance. It determines which pattern the newly entered character will belong to, as well as which pattern will be highlighted. You can move the cursor from one template to another using the cursor keys. In addition, you can always install it in the desired location by clicking there. Before entering the next character, pay attention to the position of the cursor. For example, if you enter a formula containing a fraction and place it above or below the fraction line, then the next character typed on the keyboard will be assigned to the numerator or denominator, respectively. If the cursor is at the level of the fraction line, this means that you have completed entering the fraction template and the entered new symbol will not be included in the fraction.

To move the cursor according to the formula, you should remember several hot keys and keyboard shortcuts. Using the Tab key you can move the cursor to the end of the field, and if it is at the end of the field, it moves to the next one. The Shift+Tab combination allows you to place the cursor at the end of the previous field. You can use the control keys to move the cursor one element to the right or left within the current field or template, or one line down or up. The Note and End keys move the cursor to the beginning or end of the current field.

Editing formulas

Editing a formula is practically no different from editing regular text. You can delete formula field values ​​and enter others instead. The easiest way to do this is to position the cursor in the desired formula field and then press one of the edit keys. To delete an entire template, select it and click Delete key or Space.

Note

If necessary, change the formula by applying new template, you should select the existing template together, and then select a new one from the toolbar.

When working in the formula editor, you can use the clipboard. The Edit menu contains commands designed to work with it. They can be used to move or copy formula elements. In addition, using the Undo item in the Edit menu, you can undo the last action you performed.

To complete the set, simply click the mouse button outside the field to enter the formula. In this case, the formula editing toolbar will disappear, and the window Word document will take its previous form.

To edit a formula, you need to call the formula editor. This can be done in several ways:

Double click inside the formula;

Run command context menu Formula object > Edit or select a similar item in the Edit menu;

Use the context menu item Formula Object > Open or a similar menu item Edit.

In the latter case, the formula will be opened as separate object, in a separate window of the formula editor. In addition, additional tools will be available to work with it.

Formatting Formulas

The formula editor allows you to specify the location of the formula and its elements. The first five commands on the Format menu are used to configure these settings. horizontal alignment formulas and matrix columns. In addition to left, right, and center alignment, you can use the Format menu to set equal sign and comma alignment. In this case, the formulas will be arranged vertically one relative to the other so that the corresponding signs - equals or decimal points - are located one above the other. To align the columns of a matrix, use the Matrix command.

In a ready-made formula created in the Word editor, you can change the sizes of elements. In addition, dimensions can be set before entering. The Size menu commands are intended for selecting the sizes of selected symbols in a finished formula or symbols that will be entered later when selecting dimensions for a new formula. The default size is Normal, which corresponds to font size 12. You can choose others: Large index (point 7), Small index (point 5), Large character (point 18) or Small character (12). If these values ​​do not suit you, then you can independently set the font size for formulas - the Other item is intended for this. As a result of selecting this item, a window will appear in which you can set the required values.

In addition, the formula editor allows you to override the font size of existing formula sizes. For example, if you are not happy with the 12 pt font size for the Regular size, you can set it to 14 pt or change the Small Index size from 5 pt to 10 pt. This is done using the Define menu item in the Size menu. As a result of selecting this item, the Dimensions dialog box will open (Fig. 3.3), in which you can define the types of dimensions assigned to various formula elements. When you override a dimension type, all formulas in the Formula Editor window are updated to reflect the changes made.

Transformations will be reflected in documents only after changing these formulas in the editor. In the window that appears, you can set the font size for all possible sizes of symbols in the formula editor: regular, large index, small index, large symbol and small symbol. To preview the installed changes, use the Apply button. To reject the changes, click Cancel; to confirm - OK. You can return the dimensions to the default values ​​using the Default button.

Rice. 3.3. In the corresponding window you can adjust the size of the characters.

You can set additional formatting options by choosing Format > Spacing. This will open the Interval dialog box, where you can define the size of intervals and formatting algorithms that are set by default in the formula editor.

There are many options you can change in the Interval window:

Line spacing (defines the spacing between lines of text in the formula);

Distance between rows (between matrix rows);

Distance between columns (between matrix columns);

The height of the superscript (the height of the rise of the text reference line for the superscript);

Subscript depth;

Upper limit height;

Lower limit depth;

Interval between limits;

Height of the numerator;

Denominator depth.

These parameters are set as a percentage of the normal formula size.

In addition, it is possible to configure following parameters formatting: protrusion of the fraction stroke, thickness of the fraction stroke, thickness of the additional stroke, protrusion of brackets, distance to the sign, minimum clearance, clearance in the radical, superscripts, height of the hatched character (Fig. 3.4).

Rice. 3.4. Settings additional parameters formatting

Using the Apply button, you can view all changes to the sample. Clicking the OK button will commit the changes, and the Cancel button will discard the changes. You can restore the default values ​​using the button of the same name.

Formula styles

Any set of symbols entered in the formula editor has its own style. In most cases, the necessary styles are determined automatically, but sometimes you need to set them manually, for example, when you need to enter spaces or plain text into a formula. Besides this, the most common cause Formatting errors include entering words that include abbreviated names of functions.

The following formula styles are available in the Word formula editor.

Mathematical. This style is assigned to all entered characters by default. It does not contain font definitions or character styles. When working with this style, a special algorithm is used to recognize the names of mathematical functions, such as sin, log or exp. Function names are automatically assigned the Function style; letters not related to these names have the Variable style.

Text. Selecting this style makes it easier to enter plain text into the formula. While working with it, you can use the Spacebar, as well as enter plain text into formulas created using the formula editor. Not available for this style automatic recognition and formatting mathematical symbols.

Function. Used to write notations for standard mathematical functions such as sin and log.

Variable. Used in notation of variables and constants.

Greek. This style is used to write Greek letters.

Matrix-vector. As the name suggests, it is used when entering matrices and vectors.

Using the Other item, you can independently define new symbol style parameters in the formula editor (Fig. 3.5).

Rice. 3.5. Window for defining new style parameters

You can change the style that is set automatically by using the corresponding Style menu item. To change the default settings, use the Define item. In the window that appears, you can set character formatting options for different styles. The checkboxes in the Character Format column determine whether the text is bold or italic. If you change the settings after clicking OK, all styles used in the document will be updated to reflect your choice, and all formulas will be formatted in a new way. Changes in document formulas will only be reflected after they are reopened in the formula editor.

Note

If you need to enter one character in the Greek or Matrix-Vector style and then return to the current style, you can use special keyboard shortcuts to change the style: the Greek style is Ctrl+G, and the Matrix-Vector style is Ctrl+B. For example, if you want to enter a single Greek letter (Greek style, lowercase b), press Ctrl+G and then b.

Entering text into a formula

If you need to provide a small text explanation when entering formulas, you can do this without closing the formula editor window. In the formula editor, you can write short non-mathematical phrases, such as “for all” or “except.” For such entries it is convenient to use the Text style (Fig. 3.6.). In this mode, alphabetic characters will be formatted as plain text, and you can use the Spacebar. To enter this text string After entering the formula, you need to set the Text style. Then, to switch back to the Math style, choose Style > Math.

Rice. 3.6. Entering text into a formula is possible using the Text style

Working with a formula as an object

To open a formula as an object, choose Object Formula > Open from the context menu. In this case, a number of additional features. For example, by running File > Refresh, you can refresh in text document formula without closing it separate window formula editor You can return to the Word document window by simply closing the formula editor window or using the Exit item on the File menu.

By calling the formula editor in the usual way, you will not be able to change the scale of its display, and the View menu commands allow you to select its appearance and the way formulas are presented. Working with a formula like an object does possible control formula display scale. In this case, commands for changing the scale will be available (100%, 200%, 400% and Scale), with which you can change the scale by selecting one of the fixed values ​​or specifying an arbitrary value in the Scale field. Here you can also set the display of the formula editor toolbar.

Inserting non-mathematical symbols into a formula

Despite the fact that it would seem that all the necessary symbols exist on the formula editor toolbar, sometimes the user may find that the required symbol is still missing. In this case, the easiest way out is to use standard means Word editor. You must enter the desired symbol into the document by executing the Insert > Symbol command, and then copy it via the clipboard and paste it into the formula editor window

Formula, which is Design Science's version of MathType. The program in question was developed to adapt to MS Office.

Need for use

Often, researchers and students need to enter formulas when typing in a standard text editor. For Windows OS this is MS Word. When using only the keyboard, it is impossible to achieve the correct readable appearance of the formula in a given text editor, unless the formula is very simple. In this regard, there is a need for using Microsoft Equation.

This editor allows you to create complex formulas. Formatting of the text of the latter is carried out in the settings this editor. There you can configure the font type, size and style, alignment, spacing.

Program installation

Since Microsoft Equation is part of the MS Word program, it is installed when installing this program. In turn, MS Word is installed when installing MS Office. If, after installing the latter, it is impossible to find the formula editor, it means that in the installer the checkbox to install it is unchecked by default. In order to install Microsoft Equation, you need to go to the "Control Panel", there select "Add or Remove Programs", find Microsoft Office, click on the "Change" or "Change/Delete" button. In the window that appears, select “Office Tools” and expand them by clicking on the plus sign on the left. As a result of this, a list will open in which we find the formula editor, opposite which we put a tick.

Inserting a formula in MS Word

It is carried out through the menu "Insert" - "Object". In the window that opens, you will be asked to select the object type. Select Microsoft Equation 3.0. As a result, in Word program The formula editor opens and the window prompts you to select operands for entering formulas. Wherein Word menu is replaced by the menu of the Microsoft Equation program, designed for entering formulas.

Correcting formulas

If similar formulas are entered, the need to constantly enter them may disappear if you copy the entered formula once, and then paste and edit it. Editing is done in the editor Microsoft formulas Equation. In this case, double click on the formula. As a result, this program is turned on, the formula becomes available for editing. After the formula has been corrected, you need to click the mouse outside of it, as a result of which the entered formula will become a picture and appear regular menu MS Word.

Setting up styles

IN Microsoft program The Equation Editor has a Style menu that has a number of styles that can be used when entering formulas. By default, formulas are set to a mathematical style, which already specifies which styles to apply to which elements of the formula.

To configure fonts, you need to open the menu "Style" - "Define". Here, using checkboxes, you can set whether the font is standard, italic or bold in relation to any element of the formula.

There are two fields in this window. In one field, fonts are configured. Just below is the second field in which the language is configured. In order to be able to freely switch between Russian and English languages, you need to leave the “Text” style as any.

Setting the sizes of elements

The sizes of various elements in formulas are not set exactly the same as in Word. To change them, you need to go to “Define” in the “Dimensions” menu. A window will open in which the types of elements will be listed: regular, large and small indexes, large and small symbols. On the right side of this window is a sample image of these types of elements in the formula. When you place the cursor at a size corresponding to a certain type of element, this type will be highlighted in this image.

To the right of this image are the buttons for this window. The "Default" button resets all your changes to the default settings. To confirm the changes made, you must press the "OK" button or Enter on the keyboard.

Formulas that will be entered in Word in the future will be displayed with the changes already made. Formulas entered earlier will change if they are edited, otherwise they will remain in the form in which they were originally entered.

Setting intervals

Similar to the spacing settings in the "Paragraph" menu and the "Font" menu in the formula editor, you can also change the spacing between elements. To do this, select “Interval” from the “Format” menu. In the window that opens, the intervals are defined as percentages. They are determined in relation to the normal font size that was selected in the window of the same name. Here, just like in the font sizes window, there is a view on the right. The change in interval will be clearly represented in this preview.

If you don’t like everything entered, you can restore everything by clicking the “Default” button.

Toolbar

The buttons on the toolbar are located in two rows. The top row contains symbols that can be used in formulas. The bottom row contains patterns, such as a fraction containing a denominator and a numerator. Mathematical symbols are also located here.

The spacebar when using Microsoft Equation is not inserted manually by using the same key on the keyboard. However, in the top row of the panel there is a Spaces and Ellipses button that allows you to select the amount of spacing. This makes sense if some special interval is applied or if it did not work for some reason automatic placement spaces.

Finally

MS Word 2010 included the ability to create and edit built-in formulas, but it remained possible to use the Microsoft Equation formula editor, with which you could enter formulas of any complexity into created documents.
