About Formulas

In school, you learned formulas used to calculate math problems. Microsoft Excel uses these same formulas to perform calculations in a spreadsheet.
A formula can be a combination of values (numbers or cell references) and math operators (+, -, /, *, =) into an algebraic expression. Excel requires every formula to begin with an equal sign (=).
The following table illustrates the mathematical operators learned in school and those represented in Excel 2003.

The result of a formula-the answer to 2+3, for example-displays in the cell on the Excel worksheet. The formula is visible only in the formula bar. A formula's result will change as different numbers are entered into the cells included in the formula's definition.
