In Excel, the absolute value of a cell is the cell's value without its sign. For example, the absolute value of -5 is 5. The absolute value of a cell can be found using the ABS function.

To use the ABS function, select the cell in which you want the absolute value to appear. Then, type =ABS( and select the cell whose absolute value you want to find. Finally, type ) and press Enter.

For example, to find the absolute value of -5 in cell A1, you would type =ABS(A1) in cell A2.

You can also use the ABS function in a formula. For example, to find the sum of the absolute values of cells A1 and B1, you would type =ABS(A1)+ABS(B1) in cell C1.

The ABS function can be used with other functions in Excel. For example, to find the average of the absolute values of cells A1:A5, you would type =AVERAGE(ABS(A1:A5)) in cell A6.

You can also use the ABS function to find the absolute value of a number. For example, to find the absolute value of -5, you would type =ABS(-5) in a cell.

The ABS function is a built-in function in Excel that is categorized as a Math/Trig Function. It can be used as a worksheet function (WS) in Excel.

As a worksheet function, the ABS function can be entered as part of a formula in a cell of a worksheet. For example, if you type =ABS(-5) in cell A1, the result will be 5.
