# Write Equations in PowerPoint 2007

Use the Equation Editor to place mathematical equations and expressions on PowerPoint slides. The equations you draw become embedded PowerPoint objects so you can edit them without leaving PowerPoint, even though the Equation Editor is actually a separate program. Follow these steps to start PowerPoint Equation Editor and begin constructing an equation or expression on a PowerPoint slide:

## Select Microsoft Equation 3.0 in the Object Type list and click OK.

The Equation Editor opens. You see the Equation toolbar, the menu bar, and a frame in which to write an expression. (If you don’t see the Equation toolbar, choose View→Toolbar.)

When you’re finished editing an equation, click the Close button in the Equation Editor. To edit an equation on a slide, double-click it. The Equation Editor opens on-screen.
