Could you UNCOVER THE MYSTERY behind the crystal ball?
(in the Algebraic way!)

1. I dont know and it is always wrong.

2. It will not work for some numbers.

3. I dont know how to explain this with algebra but here's my theory.

Now,if you have followed the instructions on the reader, you will end up with a number and the number's symbol will be displayed right? I have noticed that whatever number you end up with, it is a MULTIPLE OF 9.So,if you see the chart with the numbers and their symbols,you will notice that all the multiples of 9 have the same symbol!And the symbols change each time for a new try.So,if you click on the ball without thinking of any number, you will see that the symbol which appears appeared for the multiples of 9 before!

4. All the answers displayed will be correct because if you follow the instructions carefully, you would always end up with a multiple of nine answer, which is all represented by the same logo. Thus the computer changes the logo each time to make the game seem more interesting and more puzzling.

6. I know that this is going to be long winded but please bear with me. Here is my answer:
since a multiple of 9's digits always add up to 9, if you picked a number that was a multiple of 9, you would end up with a multiple of 9. if i were to show it in algebra:
let x be the closest multiple of 9 below you
let y be the first digit of x
let z be the second digit of x
