Excel is not the only Office application that lets you use formulas. Word also lets you insert formulas when you want to perform calculations; for example, if you have a table containing numbers you want to perform calculations on, you can insert a formula.

To insert a formula into a table in Word 2007:

1. Click inside the cell where you want to place the formula.
2. From the Layout tab, in the Data group, click Formula. The Formula dialog box appears.
3. Word automatically fills in the formula based on the numbers in the table and the location of the cell. If the formula is incorrect, type in the correct formula in the Formula field.
4. If necessary, use the drop down arrow beneath ‘Number format’ to select the proper format for the results.
5. Click OK. The formula is inserted into the table.
