Have Some Fun With Your 411

I saw this in one of my magazines that I was PATIENTLY reading today while I was waiting for my tires to be rotated and balanced. It was pretty cute so I thought I would share.

What To Do:

1. Multiply the first three digits of your phone number (not your area code) by 80.
2. Add 1.
3. Multiply by 250.
4. Add this number to the last four digits of your phone number.
5. Add that four digit number again.
6. Subtract 250.
7. Divide by 2.

What number did you get?
