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)

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?
