Launch the Equation Editor
How to launch the equation editor.
To use the Equation Editor, display the slide where you want to insert your equation and then choose Object from the Insert menu. On the Object Type list, double-click Microsoft Equation 3.0 to launch the program. (Or, click the Equation Editor button if it's available on a toolbar.) You'll know the program loaded successfully when an Equation Editor window, complete with its own toolbar and menus, displays. You build your formula by using a combination of buttons, palettes and keyboard entries. Just click a button from the top row of the toolbar and choose a mathematical symbol from the palette. In addition, you can type in numbers or letters from the keyboard. Finally, you can use the bottom row of toolbar buttons to add templates or preset forms. Click the template you want and then enter symbols or numbers in the slots provided to complete your formula. When you finish your formula, open the File menu from the Equation Editor Window and select Exit And Return To Presentation to close the Equation Editor.
