16. Summary One of the primary uses for Excel spreadsheets is to perform calculations. One of the primary uses for Excel spreadsheets is to perform calculations. All formulas begin with =. All formulas begin with =. If Excel cannot perform a calculation, an error value will display. You can use the Trace Error button to troubleshoot the problem.

17. Summary, continued The AutoSum feature enables you to quickly identify a range of cells and enter a formula. The AutoSum feature enables you to quickly identify a range of cells and enter a formula. The AutoFill feature enables you to quickly copy formulas to adjacent cells, and the cell references are adjusted relative to the formula’s new location. The AutoFill feature enables you to quickly copy formulas to adjacent cells, and the cell references are adjusted relative to the formula’s new location.

18. Summary, continued Format an absolute cell reference if you don’t want the cell reference to change when the formula is moved or copied to a new location. Format an absolute cell reference if you don’t want the cell reference to change when the formula is moved or copied to a new location. Displaying formulas in the worksheet can make it easier to view and proofread the formulas. Displaying formulas in the worksheet can make it easier to view and proofread the formulas. Tracing the precedents and dependents of a formula make proofing formulas quicker and easier. Tracing the precedents and dependents of a formula make proofing formulas quicker and easier.
