# 18.5: Function Library Group


The Function Library Group allows the user to utilize all of the formulas in Excel. The function is automatically inserted in the cell that is selected.

## Auto Sum

The first icon on the left is AutoSum. Autosum adds multiple cells together. After selecting Autosum, Excel intelligently guesses the range for your calculation based upon the cells around the insertion point. The user can change the cell location in the address bar.

If the user wants other frequently used commands for multiple cells, they can select the more options arrow next to Autosum. A list of options will generate.

Average calculates the sum of all the selected cells divided by the number of cells selected to find the average. Count Numbers allows the user to quickly calculate the number of cells included. Max determines the largest number in the group, and Min calculates the smallest number. More Functions launches the Functions Arguments box to allow for more options to search for a function in all categories of Excel.

## Recently Used

The recently used icon allows the user to select functions they have used most recently in Excel. This is especially helpful when performing similar calculations.
