# Perform math operations on a range of cells

Using the Calculate tool, you can apply basic mathematical operations, such as addition, multiplication, subtraction, or division, to the entire range in a click. What's more, you can add and subtract percentage or find the percentage of a number - all for multiple cells at once.

## How to do quick calculations in Excel

1. Select a range that contains the numbers to calculate in your Excel table: 2. Find the Calculate group on the Ablebits Tools tab, pick the Operation you need from the drop-down list, and enter a number in the Value field: 3. Click the Calculate button to see the result: Note. If the cell/range in your table contains a formula, it will be modified according to the operation you select. For example, you have a formula "=A1+B1" in the selected cell and you choose to calculate the percentage "- %50". When you click Calculate, the formula will change to "=(A1+B1)*0.5". In other words, this changes whole formulas, not only values.
Tip. The last 10 operations are saved in the Apply Recent list. To see the latest operations, click the Apply Recent button on the toolbar and pick the operation you'd like to apply to the selected cell or range.
