Cool Math Trick!

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

1. Key in the first three digits of your phone number (NOT the area code...)
2. Multiply by 80
3. Add 1
4. Multiply by 250
5. Add to this the last 4 digits of your phone number
6. Add to this the last 4 digits of your phone number again.
7. Subtract 250
8. Divide by 2

Do you recognize the answer ?
