How to use Excel's AutoSum feature to calculate totals?

To use Excel's AutoSum feature to calculate totals, follow these steps:

1. Open your Excel spreadsheet and navigate to the cell where you want the total to appear.
2. Click on the target cell to select it.
3. Go to the "Formulas" tab in the Excel toolbar.
4. In the "Function Library" group, locate the "AutoSum" button. It is represented by the Greek letter sigma (∑) and is usually found at the top left of the group.
5. Click on the "AutoSum" button to activate it.
6. Excel will automatically select what it considers to be a reasonable range of cells for the sum.
   • If the selected range is incorrect, click and drag to select the desired range, or manually input the desired range directly into the formula bar above the spreadsheet.
7. After you have selected the desired range, press the "Enter" key on your keyboard or click the checkmark symbol (√) in the formula bar.
8. Excel will calculate the sum of the selected range and display the total in the target cell.

Note: The AutoSum feature in Excel also works with other basic mathematical functions like average, minimum, maximum, etc. Simply click on the desired function in the "AutoSum" drop-down menu instead of directly clicking the AutoSum button.
