An Overview of SUM Function | Microsoft Excel
The SUM function is one of the math and trigonometry functions in Microsoft Excel. It can be used as a standalone function as well as in collaboration with the other functions. This article will give you an overview of the SUM function in Excel.
Objectives
The SUM function returns the summation of the given values inside the function. It accepts numbers, ranges, cell references, or a combination of any of the three.

Arguments
- number1: Compulsory. It refers to the first number to calculate the summation. It can be a numerical value (5), a range (B5:B10), a single cell reference (B5), etc.
- number2: Non-compulsory. It refers to the second number to calculate the summation. The SUM function supports up to 255 numbers.
Output
A numerical value.
Examples of SUM Function
Suppose, you want to calculate the summation of two numbers 4 and 5. The number 4 is in cell A1 and 5 is in cell A2. Now you can use the SUM function to calculate the summation of these two numbers. Just use any one of the following formulas.
=SUM(4,5)
=SUM(A1,A2)
=SUM(A1:A2)
Now here are more examples of the SUM function. Take a look.
Usage Guide of SUM Function

Step_4: Insert the first number to add.
You can directly insert a number, a cell address, or a range.
Step_5: Then insert a comma (,).
After inserting the comma, Excel will ask you for the second argument which is the second number to calculate the summation.
Step_6: Now insert the second number to add.
