|1||= 11 - 2 - 5|
The simplest Excel subtraction formula consists of the = sign, followed by two or more numbers, with the - operator in between them. This is shown in the above spreadsheet on the right.
The formula in the example spreadsheet subtracts the numbers 2 and 5 from the number 11 and returns the value 4.
|1||= B1 - B2 - B3||11|
As with all Excel formulas, instead of typing in the numbers directly, you can use references to cells containing numbers.
The Excel subtraction formula in cell A1 of the above spreadsheet on the right subtracts the values in cells B2 and B3 from the value in cell B1. Again, the formula returns the value 4.
