Using math... NOTE: this may not work on international number if you have over 7 digits... Get your calculator or start calc on your PC: Start/Run/calc and then follow the steps below: 1. Key in the first three digits of your phone number (NOT the area code) 2 Multiply by 80 3. Add 1 4. Multiply by 250 5. Add the last 4 digits of your phone number 6. Add the last 4 digits of your phone number again. 7. Subtract 250 8. Divide number by 2 Do you recognize the answer?

As I said in his rep message. That requires all 6 digits of my number less area code so I' have given him my number anyways its just a long winded way of saying "hey whats your number I'll give you a bell sometime"

quite neat. HOWEVER, as the title has stated... you can't tell me what my number is without me telling you what my number is. Steps 1 AND 5 are telling us to enter our phone number, while the other steps are side-stepping to make us think something else. lol

Yeah I have an alternative method: 1. Key in the first 3 digits of your phone number (Not the area code) 2. Key in the last 3 digits of your phone number Voila! Nice find though Mike! Reps coming your way.

Maybe so, HOWEVER, I want to know who did the math to find out this would work... It come up with YOUR phone number in addition to adding and multiplying arbitrary numbers... Kind of wierd... Mike A!

well... i think he just added/multiplied/subtracted numbers with the results in mind... see this: (example if your n° is 999 9999) (999*80*250)/2=9990000 ends up with four zeros, now you just need to add the last 4 (9999+9999+250-250)/2=9999 << this ones basically 9999 ... it add first and then subtracts/divides by 2 see? cool find btw....

Exactly. You can come up with lots of variants of this. You just need to end up with (10000x + y) where x is the number representing first three digits and y is the last four. You can do that by adding, subtracting, multiplying or dividing specific sets of values to x and y such that you eventually end up with that formula once it's simplified.
