# How to Use the Excel Sum Function in Google Sheets and Excel

We can sum entire columns in Excel using the SUM function. The SUM function takes numbers and sums them up. In this tutorial, we will learn how to add a whole column in Excel using the SUM function.

## Syntax

`=SUM(num1, [num2],...)`

## Arguments

• number1 – This argument is required. The first number. Excel can sum numbers, cell references, ranges, arrays, and constants. It can also sum the output of other formulas or functions.
• number2 – This argument is optional. It is the second number to sum. Excel can take up to 255 arguments to sum.

## How to Total Columns in Excel

In this example, we will be using a fruit sales database. Columns A, B and C have the names, unit price and sales.
