9. Now do the problems with only the keypad keys on the right on your keyboard. (Be sure that NumLock is on.)

   Whoops! There is no square root key on your keyboard. You'll have to use Help to learn how to do the square root part! The directions are buried a bit deep in Win95/98!
    

10. Open Help from the menu. On the Contents tab, open Tips and Tricks. Open the topic Using keyboard equivalents. Click on Related Topics and choose List of keyboard equivalents.

    For WinXP, in the Contents tab, open the topic Calculator and then Using keyboard equivalents of Calculator buttons.

    Whew! Finally you'll see what key does the same thing as the key on the calculator. Don't close the Help window.
     

11. Repeat the calculations using the keys on the number/symbols row.
     
12. Which way is easiest for you?
