A Math Problem...

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 your 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?

Is THIS what you are teaching your children?

(I think this would work with any number)

No. I just found it on another forum.

Neat, huh?

I also found a couple of card tricks, but I wasn't going to post those till I tested them to make sure they worked.
