# How to do sum in google sheets

When dealing with numbers one of the most useful functions is for sure the “sum”. If you have to calculate the total amount of expenses during a period, the total number of sales of a certain product or the number of employees during a shift, the “sum” function is what you need.

## Option 2 – To write the function

This is the quickest way to do a sum. You have to know the syntax of the sum function to write it down in the selected cell.

## Step 1 – Select the cell where the sum will be shown

• The suggestion is to select the cell just below the numbers to sum, in order to have a clear view of the operation. Anyway the function will work also selecting any other cell.
