A Quick thinker?

[Jenox]

This isn't a joke, but I think you'll like this mathematical quirk;

111,111,111 x 111,111,111 = 12,345,678,987,654,321

that...is freakin cool.

that works on any 1 series squared...like:

11^2 = 121
111^2 = 12321
1111^2 = 1234321

and so on...
dont know what happens when there are 10 1's though...didnt have a calcultor to do that...might check excel

edit: it doesnt work at 10: 1234567900987650000

I didn't work it out in the first place, I got it from another site.
