Cool Math Trick!

[Reefwrecker]

Pretty neat!

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?

It should still work. It boils down to 1000x + y, and it doesn't matter what x and y are.
