# Using AutoSum

You can use AutoSum to sum a range of numbers in a column or row. Click an empty cell below a column of numbers or to the right of a row of numbers, and then click **AutoSum**. Excel selects what it determines to be the most likely range of data. Click **AutoSum** again to accept the range that Excel selects, or select your own range and then click **AutoSum**. For this example, click on cell **B10**, then click on the **AutoSum icon** and then **Sum**.

Cells B5-B9 will be highlighted with the AutoSum equation in B10. Another method is to type the following in the white rectangle text box at the top of the screen **=SUM(B5:B9)**.
