    Here is a math trick so unbelievable that it will stump you.

    1. Grab a calculator. (you won't be able to do this one in your head)

    2. Key in the first three digits of your phone number (NOT the area code)

    3. Multiply by 80

    4. Add 1

    5. Multiply by 250

    6. Add the last 4 digits of your phone number

    7. Add the last 4 digits of your phone number again.

    8. Subtract 250

    9. Divide number by 2

    Do you recognize the answer?

    That is amazingly simplistic. Step 8 undoes steps 4 and 5. Take all 3 out and it still works.

    80x250=20,000
    Divide that by the 2 from the last step and you get 10,000.

    Adding the last 4 digits twice then dividing by 2 esentially equals adding the last 4 digits once.

    So all that is really being done is multiplying by 10,000 and adding the last 4 digits. Try it and see.

    (P.S. You wish you could have figured that out Molly Ringwold)
