Important The calculated results of formulas and some Excel worksheet functions may differ slightly between a Windows PC using x86 or x86-64 architecture and a Windows RT PC using ARM architecture. Learn more about the differences.
Let's say you want to find out how many inventory items are not profitable (total inventory minus profitable items) or how many employees are approaching retirement age (total employees minus employees under 55). Excel gives you several ways to subtract numbers.
What do you want to do?
Subtract numbers in a cell
Use the - (minus sign) arithmetic operator. For example, if you type the following formula in a cell:
The cell displays the following result:

Subtract numbers in a range
To do this task, use the SUM function. Adding a negative number is the same as subtracting.
Note There is no SUBTRACT function in Excel. Use the SUM function and convert any numbers that you want to subtract to their negative values. For example, SUM(100,-32,15,-6) returns 77.
The example may be easier to understand if you copy it to a blank worksheet.
How to copy an example
- Create a blank workbook or worksheet.
- Select the example in the Help topic.
Note Do not select the row or column headers.
Selecting an example from Help
- Press CTRL+C.
- In the worksheet, select cell A1, and press CTRL+V.
- To switch between viewing the results and viewing the formulas that return the results, press CTRL+` (grave accent), or on the Formulas tab, in the Formula Auditing group, click the Show Formulas button.

How you use the SUM function
The SUM function adds all the numbers that you specify as arguments (argument: A value that provides information to an action, an event, a method, a property, a function, or a procedure.). Each argument can be a range (range: Two or more cells on a sheet. The cells in a range can be adjacent or nonadjacent.), a cell reference (cell reference: The set of coordinates that a cell occupies on a worksheet. For example, the reference of the cell that appears at the intersection of column B and row 3 is B3.), an array (array: Used to build single formulas that produce multiple results or that operate on a group of arguments that are arranged in rows and columns. An array range shares a common formula; an array constant is a group of constants used as an argument.), a constant (constant: A value that is not calculated. For example, the number 210 and the text "Quarterly Earnings" are constants. An expression, or a value resulting from an expression, is not a constant.), a formula (formula: A sequence of values, cell references, names, functions, or operators in a cell that together produce a new value. A formula always begins with an equal sign (=).), or the result from another function. For example, SUM(A1:A5) adds all the numbers that are contained in cells A1 through A5 (a range). The range is one argument. For another example, SUM(A1, A3, A5) adds the numbers that are contained in cells A1, A3, and A5 (A1, A3, and A5 are separate arguments).
