# Working with Microsoft Equation

**Microsoft Equation**helps you add fractions, exponents, integrals, and so on to Word documents. You start building an equation by opening

**Microsoft Equation**:

To insert an equation in your document, on the **Insert** tab, in the **Symbols** group,
click the arrow next to **Equations**:

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 insert it into an otherwise empty paragraph, the equation defaults to appearing in
**Display** mode. If the equation is on the same line as text, it appears in **Inline** mode:

To write your own equation, do one of the following:

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

Word 2016 opens the **Equation Tools Design** ribbon:

Word 2016 provides two ways to present equations: **Professional** and **Linear**:

By default uses the professional present, but if you ever need linear, simply select the
equation(s) you want to change, and click the appropriate tool near the left end of the
**Equation Tools Design** tab:

**Equation Tools Design** 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. How to create an equation step-by step, see:
