so with the example it becomes 10*8 + 9 - (8 + 9) = 72

if you work the 10*a + b - (a + b) out you'll get:
10*a + b - (a + b) = 10*a + b - a - b = 10*a - a = 9*a

so you'll always end up with 9 times the first digit
all the multiples of 9 have the same sign, which is also the one that appears in the crystal ball... :P
Here is a rather condensed, simpler explanation (I figured it out...hooray for me!)

Looking at the chart, one can deduce that there is only a limited number of answers (for instance, you could never reach 99). Now, like in the above, lets suppose the possible answer is represented by the variable a. Now, the highest a you can reach is 81. Lets suppose 81 corresponds with the "$" symbol. If you look through the list of all the $ symbols, you will realize that these are the only possible answers. Each time you refresh the game, the symbols change, but the symbol by a is always constant.

After a while, if you wrote down every answer you got, you'd eventually find that there would be a lot of repeats (the a's), but that would take a while. So, for your convenience, I supplied the above.

But I must admit, that was pretty creepy at first.
Thanks for explaining Sara and XRds1Bnce16, because all i knew was that it had something to do with the nines and always getting a certain answer...but i couldn't deduce what was happening.
