Hi Janet71,
Welcome to the forums. To add on to what Banhein said, you actually can use the numeric keypad as a calculator, if you open the Calculator application on your computer. Here's how to do that:
1. Click the Start icon in the bottom left corner of the screen.
2. Click All Programs, and then click the Accessories folder.
3. In the Accessories list, click Calculator.
A small window with a calculator appears on your screen. With that window selected, you can now use the numeric keypad as you would a calculator, or you can click the on-screen numbers and symbols. The calculations appear on-screen in the Calculator window. I hope this helps!
