UNBELIEVABLE MATH PROBLEM

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

I would like to know who came up with this and why that person is not running the country.

Grab a calculator. (you won't be able to do this one in your Head)

• Key in the first three digits of your phone number (NOT the Area code...)
• Multiply by 80
• Add 1
• Multiply by 250
• Add to this the last 4 digits of your phone number
• Add to this the last 4 digits of your phone number again.
• Subtract 250
• Divide number by 2

Do you recognize the answer ??
