Try this. It's really cool

It only takes a minute, and it works for everyone. Pick up a calculator if you are not good at math.

1. Key in the first 3 digits of your phone number into a calculator (not the area code)
2. Multiply by 80
3. Add 1
4. Multiply by 250
5. Add the last four digits of your phone number (if the last four digits starts with zero, just use the last 3 digits)
6. Add the last four digits of your phone number again (if the last four digits starts with zero, just use the last 3 digits)
7. Subtract 250
8. Divide by 2.

This is your phone number!
