To document a formula on a worksheet, you can insert or edit an equation as an object by using Microsoft Equation Editor. You build the equation by selecting symbols from the Equation toolbar (toolbar: A bar with buttons and options that you use to carry out commands. To display a toolbar, press ALT and then SHIFT+F10.) and by typing variables and numbers. From the top row of the Equation toolbar, you can choose from more than 150 mathematical symbols. From the bottom row, you can choose from a variety of templates or frameworks that contain symbols, such as fractions, integrals, and summations.
