Did you know that you can add 9 to any digital root calculation and still have the same result as without the 9?

11 = 1+1 = 2
11+9 = 1+1+9 = 11 = 1+1 = 2

The nine basically acts like 0. With digital root, you'll always loop back around. The only way this wouldn't work is if the number you added the 9 to was 0.

I'm bored and stupid.
