all autosum function

 AutoSum is a built-in function in Microsoft Excel that automatically calculates the sum of a range of selected cells. There are several variations of the AutoSum function, including:

1. SUM: This function adds up the numbers in the selected range of cells.

2. AVERAGE: This function calculates the average of the numbers in the selected range of cells.

3. COUNT: This function counts the number of cells that contain numbers in the selected range.

4. MAX: This function returns the highest value in the selected range of cells.

5. MIN: This function returns the lowest value in the selected range of cells.

To use AutoSum, you can follow these steps:

1. Select the cell where you want to display the sum, average, count, max, or min value.
2. Click on the AutoSum button (Σ) in the "Editing" group on the "Home" tab of the ribbon, or use the keyboard shortcut Alt+=.
3. Excel will automatically select a range of cells that it thinks you want to sum, average, count, find the max or min based on the adjacent cells.
4. If Excel has not selected the correct range, highlight the range of cells you want to perform the function on and press Enter to confirm the formula.

Alternatively, you can also type "=SUM(" (or the desired function such as "=AVERAGE(", "=COUNT(", "=MAX(", or "=MIN(") into the cell where you want to display the result, and then select the range of cells you want to perform the function on. Finish the formula with ")" and press Enter to confirm.
