Actually its not that scary...its just a little math and logic. if you were to look carefully at the numbers an symbol, you'd notice that all numbers that can add up to 9 inclusive of 9 itself will have the same symbol. that means that 9,18,27,36,45,54,63,72,81 all will have the same symbol. what ever you do wiht the equation given on the site you can always only get a number divisible by nine so the site will never be wrong if it shows you the symbol for these numbers. There...logic and math!..

hahaha...
