This is interesting - try it

I would like to know who came up with this, and why that person is not running the Internal Revenue Service or my monthly expenditures. If the answer isn't obvious, you didn't do it right.

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?
