ok you dont need to show any of this info online but just do it on your calculator.

1. type in the first three digits of your cell phone.(not the area code)
2. multiply it by 80
3. add 1
4. multiply by 250
5. add the last 4 digits of your cell phone
6. add the last 4 digits of your cell phone again
7. subtract 250
8. divide by 2
and what do you get?
i thought it was kinda cool.
