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 ??????

yeah

cool

that oni heard and tried as a kid.i did not need a calculator then nor
do i need one now.for this.

that was creepy

i know

Better add the 3 digits first and later the 4 digits....
and do the calculations separately....they would eventually balance
itself !
