To add numbers in Google Sheets, you can use the SUM function, which is a built-in formula that adds up a range of cells. Here’s how you can use the SUM function to add numbers in Google Sheets:

Open Google Sheets: Open your Google Sheets document where you want to perform the addition.
Select the Cell: Click on the cell where you want the sum to appear. This is where the result of the addition will be displayed.
Type the SUM Formula: In the selected cell, type the SUM formula in the following format:
=SUM(range)
Replace “range” with the range of cells you want to add together. For example, if you want to add the numbers in cells A1 to A5, you would type:
=SUM(A1:A5)
Press Enter: After typing the formula, press the “Enter” key. The cell will display the sum of the numbers in the specified range.

Example:

Let’s say you have the following numbers in cells A1 to A5:

A1: 10

A2: 15

A3: 20

A4: 25

A5: 30

To add these numbers, you would use the formula:

=SUM(A1:A5)

After pressing Enter, the cell would display:

This is the sum of the numbers 10, 15, 20, 25, and 30.

You can also use the SUM function to add non-contiguous cells. For example, if you want to add the numbers in cells A1, B1, and C1, you can use the formula:

=SUM(A1,C1,B1)

Remember that the SUM function is versatile and can be used with various combinations of cell ranges and individual cell references to perform addition in Google Sheets.
