Step # 1 -- Open the Windows calculator

On the bottom left hand side of the screen, click the "Start" key with your "Left mouse button." The "Start" key is the blue circle with the Windows logo in it. Clicking it will open a panel. At the bottom of this panel is a button which says "All programs." Left click on it. Click the folder which says "Accessories," then choose "Calculator."

A small digital calculator should now appear on the screen. For this tutorial example, we want to know what is 30 percent of 40. On the calculator, use your "Left mouse button" to select "30 x 40/100" and press the "=" key. You should get an answer of 12.

Now subtract 8 from 40 to get 32. To perform an increase of 40 percent of 40, type in "40 x 40/100. Your answer should be 16. Adding 40 + 16 gives you 56.
