ClarisWorks provides several predefined formulas called functions. If the current cell contains a formula, ClarisWorks displays the formula in the entry bar and the result in the cell. Enter the formula after the equal sign. Confirm the entry by pressing Return, Tab. Functions simplify formulas that would otherwise be complex.
Functions consist of a name followed by one or more arguments enclosed in parentheses.
Arguments are the values you supply to a function so that it can perform a calculation. Choose Paste Function from the Edit menu. If you already know the function's arguments, you can type them into the formula yourself. In the Paste Function dialog box, select a function and click OK. to select a function quickly, start typing its name. The type of reference you use makes an important difference in the way ClarisWorks calculates formulas if you decide to move cells around in the spreadsheet.
