Here's a neat trick:

(Use a calculator. It's easier)

1. Key in the first three digets of you 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 by 2.

Recognize it? Have any idea how it works?

It should be noted this works for seven digit phone numbers.

*flails* That's creepy!

Who the hell comes up with these tricks?

My dad got it from a coworker. : )

For some reason it includes an extra number in the middle of mine, but that's still pretty odd. o_O Quite cool though.

Ooooh, works perfectly except that UK phone numbers are obviously shorter than US ones O_o

[lefcadio.livejournal.com]

ahh, so that's why the random extra number...

[bard-linn.livejournal.com]

Yeah. Apparently... XD;;

[zalia.livejournal.com]

Yeah, you have to use the third number twice (as one of the first three and as one of the last 4)

[anax.livejournal.com]

X = 1st 3 digits of your phone number
Y = last 4 digits of your phone number

X * 80 = 80X
80X + 1
(80X + 1) * 250 = 20,000X + 250
20,000X + 250 + Y
20,000X + 250 + Y + Y = 20,000X + 250 + 2Y
20,000X + 250 + 2Y - 250 = 20,000X + 2Y
(20,000X + 2Y) / 2 = 10,000X + Y

So in the end you're just multiplying the first 3 digits by 10,000 (to offset the digits the correct number) and then adding the last 4. No trick to it. :)

Very good!

[scarlette-eyes.livejournal.com]

I love math. ^_^

it didn't work with my number ecause the first number of the last 4 digits is a 0. XP

[bard-linn.livejournal.com]

You must've done something wrong. Cause I tried it with one like that. :P

[lanerose]

I'm amused. ^.^

[celes-grant.livejournal.com]

well, the first 3 were right XD the last 4 were wut? Wrong XD SHINRA LOSES AT MATHETMATICS!

[celes-grant.livejournal.com]

HAH! You lose, you didn't notice the uh, mispelling in mathematics... *yeah, it was a test, uh huh xD* ....... *shot*
