Cool math trick

[Phil77]

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?

Its suppossed to show your actual phone numbers, and it does say do not use your area code, not sure if its only good for US numbers.

this proves that if someone knows the first 3 digits of your phone number, and the last 4 digits, they can use math to figure out your phone number!! WOW!!!

 

[Thorne]

this proves that if someone knows the first 3 digits of your phone number, and the last 4 digits, they can use math to figure out your phone number!! WOW!!!

Uh...dude. If they knew the first three digits and the last four digits, they'd know your full number anyway. :rofl:

That's assuming you've got a standard 7 digit number.

 

[dirtbik3r]

haha, i wonder if thin dick rick was being sarcastic when he said the thing about people knowing all seven digits if they knew the first three and the last four .... if not oh well we all have our blonde moments lol

 

[SHOWtime]

Whoah, thats pretty cool. Nice find.

 

[Dick Hardly]

It's worked on every phone number I've used (home, cell, work, etc.). That's pretty cool and ingenius. I'm fairly convinced that if it didn't work for you, you probably did something wrong. Go back and try it again... also realize that "Add the last 4 digits of your phone number" doesn't mean "4+5+6+7," it means "+4567" (for example). I've even tried it with made-up phone numbers and it works.
