I know your phone number

[Charlesbusa]

Interesting, its simple Math though;

1. Key in the first three digits of your phone number --> (Lets say this is 'a')
2. Multiply by 80 --> (80a)
3. Add 1 --> (80a+1)
4. Multiply by 250 --> {(80a+1)x250}
5. Add the last 4 digits of your phone number --> (Lets say this is 'b') --> {(80a+1)x250} + b
6. Add the last 4 digits of your phone number again. (Add 'b' again) --> {(80a+1)x250} + b + b --> {(80a+1)x250} + 2b
7. Subtract 250 --> {(80a+1)x250} + b + b --> {(80a+1)x250} + 2b - 250
8. Divide number by 2 --> {(80a+1)x250} + b + b --> [{(80a+1)x250} + 2b - 250] / 2 = c ('c' is your phone number without the area code)

Simplifying this, we get;

125(80a) + b = c

Now 'c' can also be rewritten as [10000a + b] (Try it with your phone number, say its 7865432 = 10000(786)+ 5432)

so 125(80a) + b = 10000a + b

So Left Hand Side = Right Hand Side --> Logic

I know, I have way too much time on my hands  

Looks like somebody is a Math Nerd  

 

 

 

Good job man, yup no genius required  

Someone just took this simple formula <div class="iF-Passage"><div class="QUOTEHEAD">Quote:[/Quote]<div class="QUOTE clearfix"><span class="quoteBegin"> </span>
[10000a + b] (Try it with your phone number, say its 7865432 = 10000(786)+ 5432)[/quote]

And made it more complex so it would be cooler

Skotty:
Can you come over and balance my check book?

 

[Mr Bogus]

would you mind plotting that....

Interesting!

 

[JBradley0181]

worked thats cool

seriously, way way too much time on someone's hands

there's lots of funny calc tricks... even a dirty one that I cant post here but starts with 1 girl...

This would make for a great pick up line. Tell her just give me your first 3 digits and I will call ya in the morning  

you still need the last 4 digits to do it

Have her complete the problem while recording the keystrokes

well with questions 1 and 5 I can save a lot of time and trouble

Bingo Mr. Bogus!

You are definately the kid that my parents compared me to in school... I can hear it now.... Why cant you get good grades like Skotty

 

[pbghost]

neat stuff, even if there's a simple formula for it

 

[MR X]

Did not work for me either.???

 

[GJoker]

dont have a calculator but is the answer...yellow ?

nope.. it's a red hammer!
