# Use the SUM function to sum numbers in a range

You can use a simple formula to sum numbers in a range (a group of cells), but the SUM function is easier to use when you’re working with more than a few numbers. For example =SUM(A2:A6) is less likely to have typing errors than =A2+A3+A4+A5+A6.

Here’s a formula that uses two cell ranges**: ****=SUM(A2:A4,C2:C3)** sums the numbers in ranges A2:A4 and C2:C3. You’d press Enter to get the total of 39787.

To create the formula:

- Type
**=SUM**, followed by an opening parenthesis**(** - To enter the first formula range, which is called an
*argument*(a piece of data the formula needs to run) type**A2:A4**(or select cell A2 and drag through cell A6) - Type a comma (,) to separate the first argument from the next
- Type the second argument,
**C2:C3**(or drag to select the cells) - Type a closing parenthesis
**)**, and then press Enter

Each argument can be a range, a number, or single cell references, all separated by commas.

** Tip ** If you need to sum columns or rows of numbers that are next to each other, use AutoSum to sum numbers.
