Bizarre math trick

[academic punk]

Someone obviously has way too much time on their hands.

Here is a math trick that stumped me. 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 ?

Well the final answer I got was my full ph. number. I'm sure there's a logical reason.

I found that myself one day during a Math Test...
I was bored..

Ah, c'mon...you can read that a mile away when you're doing it. Now if it DIDN'T ask for the last four digits of your phone number, then that would be impressive.
