It's based on mathematical calculations. You can take any 2-digit number and perform the given calculations, the result will always be a multiple of 9.
If you look carefully, you will notice the same thing written on all multiples of 9. It (the software) just keeps changing the regift on every next attempt, while keeping a similar regift on each multiple of 9.

interestingi got it.it doesnt use any calculation or anything.it just detects on which number you put the cursor,and then tells you that number.if you put the cursor on a number and then move it to another number,it would then tell the number you put the cursor first. clever.

Nope. It does not have anything to do with the cursor. I think AabiruSabeel is right
