Cool Math Trick

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?

Nice little trick...

tip for Twinkletoes...in order to make it work for a 6 digit phone number, use 25 instead of 250 :cool2:

..finally the math degree comes in handy for something!
