Calculate - Excel on Computer

Microsoft Excel can be used as a calculator. The following example shows subtraction. You can use other symbols to add, multiply, divide, and perform other calculations.

  1. Double-click on a cell to begin editing it. Type a formula for subtraction and use cell references.
  2. Press "Enter" or "Return" on the keyboard to commit the changes to the cell. Then click on the cell again. This will place a small square at the bottom right of the cell.
  3. Drag the formula across multiple cells. Move the cursor over the small square so it turns into a very small + symbol.
  4. Click, hold, and drag that square to apply the formula to other cells.
The image shows callout number one pointing to the formula in cell L2. Callout number two is pointing at the result of the formula once you click enter. Callout number three is pointing at the plus symbol that appears at the bottom right corner of cell L2. Callout number four is pointing at the arrow that follow the range of cells that are selected under the Final Price column.
