Note

Office 365 ProPlus is being renamed to Microsoft 365 Apps for enterprise. For more information about this change, read this blog post.

Symptoms

When you try to edit an equation that was inserted using Equation Editor 3.0 in an Office application (such as Word), you see the following error:

Microsoft Equation is not available

Cause

Equation Editor 3.0 was a third-party component built by Design Science (https://www.dessci.com) that was included in many versions of Office, but due to security issues with its implementation has been removed. Office now includes a newer equation editor.

Resolution

While the new equation editor will not edit existing equations that were created by Equation Editor 3.0, it allows you to insert new equations, common equations, or ink equations written by hand. The equation function can be found in Word, Excel, or PowerPoint under the Insert tab.

For more information about inserting and editing equations, including a short video tutorial, see Write an equation or formula.

Alternatively, the third-party app MathType enables you to edit Equation Editor 3.0 equations without security issues. MathType is now part of the Wiris Suite. You can download a free MathType 30-day trial at: Welcome Microsoft Equation Editor 3.0 users

## Equations Are Displayed As { Embed.equation } In Microsoft Word

The information on this page applies to:

MathType for Windows and Mac

Equation Editor (e.g., Microsoft Equation 3) for Windows and Mac

All supported versions of Word for Windows and Mac

Many users become alarmed when the equations in their Microsoft Word document is displayed in the cryptic form of { EMBED Equation.DSMT4 } or { EMBED Equation } instead of the actual MathType or Microsoft Equation equations.

These representations are a feature in Microsoft Word called Field Codes. They are used to help Word identify objects, such as equations, in your document. You only see them when the option is turned on, in which case they appear on-screen, in print, or both on the screen and in print.

{ EMBED Equation } or { EMBED Equation.DSMT4 } on screen

If you find that your equations are not displaying on-screen but instead are displaying something like { EMBED Equation } or { EMBED Equation.DSMT4 }, you can change your view settings in Word to correct this. To do so,

Uncheck the box for “Field Codes” or “Field codes instead of values”.

Press OK (Windows) or close Preferences (Mac).

At this point, the equations contained within the Word document should display correctly. Other ways you can toggle this property are:

Via the Word toolbar; the toolbar button in Word looks like “{ a}”. This is not one of the default buttons but can be added to the Word toolbars by using Word’s Customize command. For more information about customizing your Word toolbars, please consult your Microsoft Word online help.

Any of the above methods will allow you to toggle the field codes off and on that will allow you to see the equations.

{ EMBED Equation } or { EMBED Equation.DSMT4 } in print

If you find your equations are not printing but instead are displaying something like { EMBED Equation } or { EMBED Equation.DSMT4 }, you can change your print settings in Word to correct this. To do this:

Select the Print button (Mac) or Advanced/Print (Windows).

Uncheck the box for “Field Codes” or “Print field codes instead of their values”.

At this point, if you print your document, the objects contained within the Word document should print out correctly.

We hope this has been helpful. As always, please let us know if you have questions about this, or if you have additional techniques that work. We’d love to hear from you.

## Insert Math Equations In Word 2013

Use formulas in Word 2013

Inserting math equations is one of the most important features of Word 2013. It is very useful when you want to insert a math equation in your documents. Someone might want to make a document, such as a business manager, finance manager, school teacher, university professor and for them Word provides the facility to add mathematics equations or symbols in their report. However you can insert the math equation and symbol by hand but it looks more professional using the Word built-in feature.

Use the following to insert the math equation in your documents.

Step 1

First of all open the document that you want to insert a math equation into and place your mouse pointer where you need to insert it.

Step 2

Step 3

Step 4

Step 5

The drop down button of equations contains two options, “professional” and “linear” that help to change the look of the equation and changes it to inline in order for the option to change the location of the equation.

Step 6

Step 7

You can also add a new equation by choosing “Insert New Equation” within the equation drop down list.

Step 8

Now Write your own equation using symbols, structures and tools.

There is one other way to add the equation to Word documents; that is by using the Microsoft Equation 3.0 object.

Step 9

Step 10

Step 11

A new window will be opened where you can choose the equation you need. But Word 2013 will treat this as a Microsoft Office Word’s object. It is the main difference between this equation and a previous equation.

## How To Edit Conditional Formatting In Excel

You can edit an existing rule if the criteria have changed or if you simply want to update the format. The Rules Manager allows you to manage all aspects of conditional formatting—creating, editing, and deleting rules.

Edit a Conditional Formatting Rule

Select Manage Rules.

The Conditional Formatting Rules Manager, where you can edit or delete existing rules, opens.

Select the rule you want to edit.

The Edit Formatting Rule dialog box displays.

Make your changes to the rule.

The preview at the bottom of the Edit Formatting Rule dialog box updates to reflect any changes you’ve made to the rule.

The rule is updated and any cells in the workbook using that rule update accordingly.

When there are multiple rules applied to the same range, two or more rules could apply to a single cell. You may need to change what order the rules are applied to give priority to the most important format.

Select Manage Rules.

When there are multiple rules listed for a selection, they will be applied in the order they appear here, with the one at the top of the list taking precedence.

Select the rule you want to resequence.

The conditional formatting rules are applied according to the new sequence.
