Formulas and Functions

Abstract

It is in formulas and functions that Excel’s true power resides because it is through them that calculations and evaluations are processed and relationships between items of data are created. Formulas can range from simple addition or subtraction calculations to formulas that handle nonnumerical data and more sophisticated three-dimensional or array formulas. Functions are basically predefined formulas built into Excel to facilitate complex or cumbersome calculations and to enable you to carry out a wide variety of analytical tasks. Most of Excel’s analytical tools, like the PivotTables or data tables discussed in previous chapters, are simply user-friendly facades for the multiple complex formulas and functions required to produce particular analyses and reports.
