Use Equation Editor in Excel 2007 for WindowsTo document mathematical formulas 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 Equationtoolbar and by typing variables and numbers. In the top row of

the Equation toolbar, you can choose from more than 150 mathematical symbols. In the bottom row, you can choose from a

variety of templates or frameworks that contain symbols, such as fractions, integrals, and summations. The Equation Editor

provides symbols that are not available on the keyboard (for example, Greek letters and the square root symbol) in a logical

grouping so that you can easily build equations.

You can also create an equation in Microsoft Office Word and then copy and insert that equation object into your worksheet. You

may find that the Equation Editor in Word makes it easier to find the symbols and structures that you want. Word also provides a

gallery of commonly used equations that you can easily copy and paste into your worksheet.

In the preceding picture, cells A2 and A3 contain Excel formulas that return values. Equation objects that express the same

function in mathematical terms are embedded on top of the adjacent cells B2:C2 (a formula that calculates the future value of

10000 at 5 percent interest compounded annually over a three year period) and on top of cell B3 (a formula that calculates the

square root of 729). These objects are not contained in the cells, and don't perform any action  — you can think of them as

images of text that describe the formulas in the cells in column A.
