Unbelievable Math Problem

Here is a math trick so unbelievable that it will stump you.

Personally 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). [edit- any 7-digit number will do]

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?

((80x +1)250 +2y -250 )/2

=(2000x +250 +2y -250)/2

=(2000x +2y)/2

=1000x +y

I don't like these myself. I get lots of things like these by email, they are clever but they aren't really that amazing, it's just maths. You can make almost anything mean anything if you really really want to.

That's the very thing that's cool about it. Somebody had the imagination and skill to build the equation. He/she has used math as an art medium.
