Which button do you click to add up a series of numbers?

Spreadsheet software provides dedicated one-click tools on the ribbon for the most common calculations, so a user does not have to type a formula manually every time. One such dedicated tool automatically totals a selected range of numeric cells.

In Microsoft Excel, this dedicated tool is the AutoSum control (shown as the Σ, sigma, symbol on the Home tab). Selecting a range of numbers and clicking it inserts a SUM formula referencing that range and displays the total in the adjoining cell — exactly the action the question describes.

• Formula button: Excel offers general formula-building tools (typing a formula manually, or using Insert Function), but no ribbon control carries this exact name for one-click summation.

• Quicktotal button: no tool or menu command by this name exists on Excel's ribbon.

• Total button: Excel has no ribbon control with this generic label; the actual one-click summation tool has a specific, different name.
