AutoSum in Excel

AutoSum is a function in excel that automatically adds from a selected range of cells. To do this, all you need is the AutoSum button. On the Home tab, it's in the Editing group.

The AutoSum button can do more than add.

1. Click the down arrow next to the AutoSum button. 
2. Then click any of the functions on the list that appears:
   • Average
   • Count
   • Max
   • Min
3. If you click More Functions, Excel opens the Insert Function dialog box where you can choose from all of the Excel functions. Or click the Formulas tab and check out the Function Library and Calculation groups.
