Lol...its one of those things where what ever you choose it will have the same number, you will find the answer somewhere in the internet.

multiple of 9 ..... take an example: 18 so after couting the 1+8 of the 18 you have 9. Now 33 -> 3+3 = 6 - 33 = 27 = multiple of 9. Check the images on 9 - 18 - 27 - 36 - ..... they are all the same
