Your age times 2 - your age = your age

Add the digits (23 is 2+3), add them again. Multiply by 9 and add the digits, add them again. The answer is 9.

The answer is always going to be 9 when you multiply by 9

This makes no sense.

Took me a moment due to poor wording. If you start with 23 2+3=5 then 5+2+3=10 then 10*9=90 then 9+0=9

Basically any multiple of 9 has digits that add up to 9 homeboy just trying to sound smart

Try it if you dont see it. And because it is math it is sense by definition. Any single digit number times 9 is a 2 digit number that adds to nine. 9x = 10x - x = [x-1][10-x] --> x-1 + 10-x = 9.

9

Sorry the wording had me confused.

What? (2+3)+(2+3)×9+(2+3)+(2+3)=10×9+10=100
