Insert a formula

Use formulas and functions in tables in the iWork apps—Numbers, Keynote, and Pages. Formulas can be as easy as typing an equation like you might in a calculator, or you can add complexity with cell references, functions, and wildcards. To get started, just type the equal sign in an empty table cell to open the Formula Editor.
