It was wrong 2 out of 5 times.

You should re-check your math. It's mathematically based and shouldn't be wrong that often.

It's never wrong. It's like a nines compliment code.

10-1=9, 20-2=18, 30-3=27, 40-4=36, 50-5=45, etc.
11-2=9, 21-3=18, 31-4=27, 41-5=36, 51-6=45,
12-3=9, 22-4=18, 32-5=27, 42-6=36, 52-7=45,
13-4=9, 23-5=18, 33-6=27, 43-7=36, 53-8=45,

etc

For each new screen all numbers divisable by 9 will always have the same symbol, therefore it can never be wrong.

Mine was wrong too.

Have you seen it before, Idiot, or did you figure out how it works on your own? I had an idea how it worked, but had to look it up for all of the details.

I thought it was wrong on a couple occassions, but it turned out the first time I wasn't following directions properly and the second I had the math wrong (did it too quick in my head).

I've seen similar recurrent operations but not this one. The crystal ball is supposed to show you the symbol next to your final answer.

Since we know that your final answer will always be a multiple of nine, if you just look at the symbol next to the number "9", you'll also notice that all multiples of nine (18, 27, 36,...) will have the same symbol next to them. Now click on the crystal ball and that will be the symbol shown.

It doesn't matter what number you pick. It can't be wrong.

ya-huh. math geeks
