Cool Math Trick

This math trick is really cool. Just try it!
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-if your number is 01-123-4567, the 1st 3 digits are 123)
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?

x = first 3 digits of phone number
y = last 4 digits
=[250(80x+1) + (2y - 250)] / 2
=[20000x + 250 + 2y - 250] / 2
=[20000x + 2y] / 2
= 10000x + y
= your phone number :)
guess it dont work with english phone numbers.
Put them next to eachother in that same order.
tadaa!
BTW if you want one that works with UK phone numbers (if you hate life) then try this :
take the first 3 digits of your phone number (not area code) and multiply them by 24
add 5
multiply by 125
Add the last 3 digits of your phone No.
Add the last 3 digits of your phone No. again.
Add the last 3 digits of your phone No. again.
divide it by 3000000 and add the digits of your area code then divide by 1000. (you need a computer calculator to display all the digits.
TA-DA! another stupid trick!
also, divide by 10000 not 1000
I have 7 in mine, not including area code.
It should work with any number. Doesn't matter anything as long as you put 3 digits for the first number and 4 digits for the second.
Here is the trick as Jason proved too.
answer = [{[(n*80)+1]*250}+2*y-250]/2;
= [{(n*80*250)+1*250}+2*y-250]/2;
= [n*80*250 + 250 + 2*y - 250]/2;
= [n*80*250 + 2*y]/2;
= n*40*250 + y;
= n*10000 + y;
So if n = 123 and y = 2345, then
answer = 1230000 + 2345 = 1232345
if n = 001 and y = 0879, then
answer = 0010000 + 0879 = 10879 = 0010879
So, strange?? yes or no :p
take the first three digits of your telephone number, multiply them by 10 and the result is the times you gotta shove a broom up your ass.
taaaa-fuckin-daaaaaaaaaaaa.
This from a person who's county is run by someone called "Bush". Who said you guys had no sense of humour.
No offense to normal americans which most of you are, and your country does have many good things but alas there are some nobheads which seem to take pride in the wrong things and feel their country looks better by slating someone elses so i thought he should have some of it in return as anything else would have gone over his head.

Wasnt it the English who started the internet, now thats something to be jealous of.

No, but neither did america. The Internet was invented by CERN in switzerland.
"there is a Asteroid by the name of apophis that is going to wipe us out in 29 years. Google and you'll see for your self"
Actually Google won't turn up much at all but a wiki search indicates that this asteroid is no threat at all.
Thats aimed at the gung-ho wannabe heroes that turn a post about a maths trick into a race hate...shame on you!.
Now going back to the ACTUAL topic in hand...the trick is mildly amusing but as plenty have said..its dependant on your number not having a zero at the start of either the first three or last four numbers...and I'm leavin it there cuz anymore talk on this is a distraction from nickin another movie :).
Where it says the "first 3 numbers" if your number is more or less then 7 digits you simply take "the number of digits in your phone number, subtract by 4"
IF your number starts with 0 then it won't work and its just bad luck for you coz the rest of us have numbers which start with a non-zero.
6. Add the last 4 digits of your phone number
7. Add the last 4 digits of your phone number again
So, if your last 4 digits are 4587, DO NOT add 4+5+8+7, but add 4587.
try it out!
1. take a calculator
2. type in "12345679" (no 8)
3. times it by any number multiplied by 9,
lets say you want 5, 5*9=45, so 12345679*45=?
try multiplying by: 9,18,27,36 and so on...
WE(canadians) don't live in iglos and our bankin machines are not made of ice
But this trick is lame. It would have been kewl if it really was something useful, like finding another part of a phone number or other info using some part of it with some math calculus.

you're all wrong. ARPANET, the precursor to the internet was an [b]American[/b] project. In to 90's CERN was the one who was responsible the WWW project and the first ever web pages.
37 * 3 = 111
37037 * 3 = 111111
37037037 * 3 = 111111111
37 /3 = 12.333
37037 /3 = 12345.666
37037037 /3 = 12345679
oh here's another trick for squaring numbers
X^2 = (X-1)(X+1) + 1... and also
X^3 = ((X-1)(X+1)X) + X... because you just take the first equation and multiply by X
it's all simple grade... something math... you could even do
X^2 = (X-73)(X+4) +292, if you wanted to...
2. Key in the first two digits of your phone number, the 1st 2 digits are 123)
And if your phone number is 7 digits then in the step 2:
2. Key in the first three digits of your phone number, the 1st 3 digits are 123)
and so....
Example for those who STILL don't get it:
Phone number: 987-6543
987 * 80 THEN PRESS EQUAL
You get your answer then ADD 1 then PRESS EQUAL
and so on and so forth.
And to the dense fuck that said "fucking nerd cunts", at least we use our brains for something; the only thing you probably do is give all the blood in your head to blood boy down there. gtfo. kthxbye.
hey, peeps try this..its so fuckin funny!!!
