dude, simple explanation
whatever 2 digit number you start out with, the result can only be a multiple of 9 - which is 0,9,18,27,36,45,54,63,72,81 - and if you look at the symbol, they are always the same !!! - the one that is going to show up which you click that farking crystal ball !!!
put it mathematically, suppose your 2 digits is ab
the number you get is (10*a+b)-(a+b)=10a+b-a-b=9a
your answer will always be 9 times the first digit ...
e.g. if a=4,b=5, your original 2 digit number is 45
so 45-9=36 which is 9 times 4 !!! |
