The answer is always a multiple of 9 and all multiples of 9 have the same symbol.

This is scary!!

[ChuckFickens]

OH, sorry, that one is a different one....

Hold up :)

[sadielady]

I have done it 3 times, different numbers and symbols each time - it worked each time

[merciasounds]

I know...scary indeed - as you don't click on anything - how does it know!!

But chuck, it's not always the same symbol (the one for multiples of 9) that comes up when you click the crystal ball.

[ChuckFickens]

OH, OK...

Right it doesn't matter what numbers you start with, the answer will always be a multiple of nine

Start with 25, 2+5= 7
25-7= 18

so 2 nines

start with 47
4+7=11
47-11=36

so 4 nines.

Start with 18 (should b easy to see how it's done)
8+1=9
18-9=9

So one times nine.

I meant don't click on anything first - you make your choice, do the math THEN click the crystal ball!

[ChuckFickens]

Karren, look at the symbol for 9 and it changes every time, as do all multiples of 9

Ah, I was assuming the symbols on the right stayed the same Chuck :)
