Okay, This Is Bizarre.
 

Try to fool it:
Crystal Ball

Explanations welcome.

The sight doesn't come up for me. :frown:

"There is a theory which states that if ever anyone discovers exactly what the universe is for and why it is here, it will instantly disappear and be replaced by something even more bizarre and inexplicable. There is another that states that this has already happened."

-from The Hitchhiker's Guide to the Galaxy

Way to go, AFGNCAAP. You shattered the crystal ball.:P What now, O Destroyer of Worlds?

Brilliant reasoning, AFGNCAAP!

Apparently you've shattered it for good! :D

Try to fool it now!

That's disappointing.

It's a trick that bookkeepers use to find a transcription error - if you've reversed two numbers in one column and it doesn't match another column that it should, the difference between them will be divisible by 9 if you've reversed two numbers - ie 45 and 54, 61 and 16.

You must be pretty good if you were able to get that when the page is down!

Bah! Piece of cake! (even if you weren't referring to me)

It worked, fooled it on the third time without even thinking about fooling it. Yes, I'm sure I'm the first one ever to do that.

It was spooky on the first few times though :P

Don't mind if I do, ta! :D

Quite right though. As a sort of book-keeper myself the first question I ask someone who comes up with an error is how much the difference is. Divisible by 9? Transposition error!

t's amazing how much time it saves when you know that's what you are looking for.

How nice to have one's opinion backed by competent authority! Thanks

Well that was pretty easy to figure out, actually. Wierd number trick though.

As far as number riddles go, this one is pretty lousy. Not quite as bad as the "Now subtract the number you started with..." ones, but close. Here's a better one:

Take a number. Any number, doesn't matter what kind. Just for example, let's say seventy-four, because I like seventy-four. Then you count the letters. The word "seventy-four" has eleven letters. So now we take "eleven"- six letters, so we get to "six". Keep going until you reach the end- you'll know it when you see it. Try this with any number, and see what happens!
