The SUM function is one of the most utilized functions in spreadsheets. The syntax is easy to remember and works the same across most spreadsheet programs. In this article, we are going to explore its usage in spreadsheet.com.

## Purpose

The SUM function returns the total of a series of numbers, cells, or both.

## Video Explanation

## Syntax

`=SUM(value1, [value2,...])`

`value1`

– The first number or range to add together.`value2, …`

– [OPTIONAL] Additional numbers or ranges to add to value1.

## Examples

### Example 1 – Sum Values in a Continuous Range

In the above image, you can get the total sales to figure using the formula `=SUM(B2:B9)`

. The dataset, in this case, is continuous, so you only need to specify the range to add together inside the function. What if we were working with scattered values that are not necessarily in adjacent rows or columns?

### Example 2 – Sum Values Across Non-Adjacent Cells

If the values we wish to add are not adjacent to each other, we have to tweak the formula a little bit. In the above dataset, we’d like to exclude Paul and Jessica from the summation. The formula would change to `=SUM(B2:B4, B7:B9)`

. As a result, the total this time excludes Paul and Jessica’s sales.

Note: The SUM function has some shortcomings, such as accidentally double counting when multiple SUMs are in a column. Every cell given as input to the function is added, even if it is already a subtotal. In such instances, the SUBTOTAL function might be more helpful as it can ignore other subtotals.
