Microsoft Excel may be known for complex calculations and formulas, but it’s no slouch at simple arithmetic. There are a number of ways to find solutions to simple math problems, like finding the sum of numbers in multiple cells.

Finding the Sum of Numbers in Adjacent Columns or Cells

The quickest way to calculate the sum of squares in Excel is to simply highlight the list of numbers, and check the bottom right of the screen. Here, you’ll find the sum of any selected cell as well as their average and the number of cells you’re adding.

But, we’ll assume you want to add the sum to the workbook itself. In that case, highlight the numbers you want to add.

From the “Formulas” tab, click “Autosum” to find the sum of the list of numbers. Once you click, Excel will automatically add the sum to the bottom of this list.

Alternatively, you can type the formula =SUM(D1:D7) in the formula bar and then press “Enter” on the keyboard or click the checkmark in the formula bar to execute the formula. Change the letters and numbers in parenthesis to fit your workbook.

Finding the Sum of Numbers in Non-Adjacent Columns or Cells

Click any empty cell in the workbook. This should be the cell where you want to display the sum of these non-adjacent columns.

To add the second column of numbers, hold Ctrl and scroll down from the first to the last number in the column. Alternatively, you can add the formula =SUM(D1:D7,F1:F7) to the formula bar. Swap the cells inside the parenthesis to fit your needs.
