This came to via e-mail; it was neat so I thought I'd share!!!
Here is a math trick so unbelievable that it will stump you.
Personally I would like to know who came up with this and why that person is not running the country.
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?
