Saw this on another forum i visit and thought i'd share....


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.

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

1. Key in the first three digits of your phone number (NOT the area code...)
2. Multiply that answer by 80
3. Add 1 (ONE)
4. Multiply that by 250
5. Add to this the last 4 digits of your phone number
6. Add to this the last 4 digits of your phone number again.
7. Subtract 250 from the total you have
8. Divide that total number by 2

Do you recognize the answer ??

 

woo my phone number

 

lol, I love it!... nice find.

111,111,111 X 111,111,111 = 12,345,678,987,654,321 Kinda interesting palidrome.

 

well.... i dont want to take too much credit, but i was the one who invented that... muhahahaha

that was sick.

 

Neat little trick. The engineer in me is gonna force me to figure this one out.

 

Iwould be more impressed...but seeing as how you input both sections of your phone number it is just a matter of arithmatic manipulation. Not saying i could come up with this, but i want to see a series to output the second section with only the input of the first. THAT would be a nice party trick.

 

1. input first three number of your phone number (not area code)
2. multiply by 10000
3. add to the last 4 digits of your number
4. subtract 20
5. add 20

look familiar?

 

i can do one better:

1. input your phone number
2. look familiar?
