I mean, whoever came up with this just did it with trial and error, or what? How would someone come up with the "procedure" to do this?
Enter the following in a calculator: Enter the first three digits of your phone number (the exchange, not the area code) Multiply by 80 Add 1 Multiply by 250 Add the last 4 digits of your phone number Add the last 4 digits of your phone number, again Subtract 250 Divide that number by 2 The result is ? 


intersting...


"It's good to know who hates you, and it's good to be hated by the right people."

The result is nothing I understand. What are you getting at?
Do you mean add the last 4 digits of your number as in 3456? Or do you mean the last 4 digits as in 3+4+5+6 equaling 18? 


The result is your whole phone number. 


I tried two different phone numbers and none of them worked. Maybe i am doing it wrong 


Heh, that's kinda weird...


dude, come on, how can you go and do something like spell 'no' wrong?  me
Try to look unimportant, they might be low on ammo.  unknown 
If your number is (789) 1234567, you use the 123 part and the 4567 part, not the area code. The result will be 1234567. 


Hey, I've got another great trick!
First, give me your social security number... <BR>

ok, thats weird....



It's Algebra



The way the problem is stated: C = {[A(80) + 1]250 + B + B  250}/2 = { 250(80)A + 250 + 2B  250 }/2 = 125(80)A + B = 10000A + B A = your exchange B = the last 4 of your phone number That's how it works. Now take any number  type it into your calculator, then  type the same digits in again (for example, 247247)  divide by 13  divide by 11  divide by 7 What is the result? 


Calculate this algebraically.
Let x = first three numbers let y = last four numbers (80x + 1)*250 +y + y 250  = 2 250*80x + 250 + 2y 250  = 2 10000*x + y The first three digits of your phone number times 10,000 will add four zeros to the three digits, then add the last four digits to get to your original phone number. This is no big deal. It ain't rocket science. 


alright, its working for me now.



Thanks. That's what I was looking for. Not only do I suck at math (I changed my major from engineering to a more friendly accounting back in college) but I don't think I could do long division anymore, much less anything else. 


Here's a really crazy one too.
1) Type the first three digits of your phone number into a calculator. 2) Pause for dramatic effect. 3) Type in the remaining four digits. 4) ...

Whoa! It comes up with the phone number!!! 


nm by the time I finished typing someone had already posted :P
