Try this.

It's pretty cool. I even tried throwing a 5 digit number at him, and he still got it right.

Finally figured it out.

Neat trick.

If you want to try something really fun, work out how the trick works

Um, my math must have been wrong, because it didn't work.

Well, I just found it doesn't work if you use the same numbers, like 1111 or 222. Or if you do any numbers that switched around and subtracted equal 0, like 3232.

Well, it does work with the same numbers, you're just not allowed to pick zero. Plus, since numerals are not differentiated, in the first case you can't scramble them up, and in the second you aren't .

Um...I think I'll go work on my physics now. It's less confusing.

I'll try to figure out the formula later.

Someone please tell me how it works???

I can't get that website to even load .

ok i know how it works!

clearly computers actually can read minds, just like the one with Darth Vadar

Well, I haven't found a formula yet, but I think I know how it works. Maybe.

It's based on an old bookkeeper's trick.

Okay ... and since the number is always divisible by nine, its digits ADD UP to a number divisible by nine, which means that all the program does is add the digits you type in, divide that number by nine, subtract the remainder from nine, and there's your answer. Clever!

It didn't get mine.

cool...I didn't work it out yet, though.
