Amaze your friends, well maybe amaze is too strong a word

    Here's a neat little trick I just learned:
    Tell your friend to write down a 3 or 4 digit number, but don't let you see it (it can actually be any number of digits over 2, but if your friends are like mine they get confused easily). Tell them to use a variety of different numbers. Let's say our friend picks 1234. Now tell them to rearrange those digits into a new number, like 4321 or 2143 or 3241 etc, again don't let you see it. Let's say they pick 4123. Now tell them to subtract the small one from the big one. 4123-1234=2889. Now tell them to circle one of the digits in their answer, but don't circle a 0, cause it's already a circle. We'll say they circle the 9, tell them to take the uncircled digits and rearrange them and tell you that number, 288 or 828 etc. and you will tell them what digit they have circled. Someone want to try? Then I'll tell you how it's done, although once you look at it closely you'll probably figure it out. It is pretty neat though.

    Just call me "Nostrildumbass"
    should I say how the trick is done, or should I let people try to figure it out?

    Let's wait a while and see who else want to test your mighty brain :P

    I've got one too: you should follow your initial hunch!

    Pick a two digit number between 1 and 50
    The number cannot have two digits the same,
    It can only be an ODD number.

    wow, amazing, wrong, but amazing

    sorry, I think I misread your instructions. I just picked an odd number, you meant both digits have to be odd right? sorry. plus I saw this trick on some TV show. so I shouldn't have even participated, and once participating I shouldn't have screwed it up.
