Excel Formulas and Functions For Dummies, 2nd Edition

Excel becomes far more useful when formulas do more than add a column of numbers. Excel Formulas and Functions For Dummies, 2nd Edition helps readers understand how formulas are assembled, how to choose functions, and how to apply them to everyday calculations and data tasks. Its examples range from loan payments and classroom grades to investment calculations and database organization.

Start with the logic behind a formula

Ken Bluttman and Peter Aitken begin with the essentials: worksheets, cells and ranges, references, function arguments, and ways to enter formulas. The opening chapters also address arrays and common errors, including mismatched parentheses, circular references, and broken links. That foundation helps make the later examples easier to follow—and easier to adapt.

Put Excel to work on practical calculations

The book explores financial and mathematical functions for tasks such as calculating loan payments and interest, working with depreciation, summing and rounding values, and using trigonometry. These examples show how a function can turn a routine spreadsheet calculation into a repeatable formula.

Make sense of data, dates, and predictions

Further chapters cover descriptive statistics, significance tests, probability, and forecasting, including functions for examining trends and estimating outcomes. The guide also works through date and time calculations and functions for handling text and database-style information.

A guided reference for Excel 2010

Organized by topic, this second edition suits readers who want to build their understanding step by step or look up a function for a particular spreadsheet problem. It was written for Excel 2010; readers using later versions may notice differences in the interface or available functions, while the book’s core lessons in formulas and spreadsheet reasoning remain the focus.
