# Working with Microsoft Equation

**equation**is a mathematical statement that two mathematical expressions are equal (indicated by the sign =).

**Microsoft Equation**helps you type fractions, exponents, integrals, and so on in Word documents. In addition, Word allows you to insert an equation from the

**Gallery**, create a new equation, edit, change, or delete a part or the entire equation.

## Insert an equation in the Word document

To ** insert** an equation to the Word document, on the

**Insert**tab, in the

**Symbols**group, click the arrow next to the

**Equation**button:

You can use the vertical scroll bar in the **Gallery** to display additional equations (how to add an equation into the **Gallery**, see How to add your own equation to the Equation gallery). If you see what you want, click it to insert it at the current insertion point in the document. If you add it into an empty paragraph, the equation is rendered in **Display** mode. If the equation is on the same line as text, it is rendered in **Inline** mode:

## Create an equation

To ** add** a new equation, do one of the following:

- On the
**Insert**tab, in the**Symbols**group, click the arrow next to**Equation**, and then click**Insert New Equation**, - On the
**Insert**tab, in the**Symbols**group, click the**Equation**button, - Or simply press
**Alt+=**:

## Working with equations in Word

Word for Microsoft 365 opens the **Equation** tab:

Word for Microsoft 365 provides two formats of equations: **Professional** and **Linear**:

By default, Word uses the **Professional** representation, but if you need **Linear**, do one of the following:

- Select the equation(s) you want to change, on the
**Equation**tab, in the**Conversions**group, in the**Convert**drop-down list, choose the appropriate option: - Click the down arrow to the left of the equation, then select the appropriate option from the context menu:
- The
**Equation**tab contains dozens of equation templates. Within each button on the toolbar, there are several tools available. Simply click on a button to see the tools contained in each.
