9+10=21
9 breaks to 3"3.
10 breaks to 5"2.
3"5=15 and 3"2=6.
15+6=21
Therefore 9+10=21
The math has been done.

I actually never used " in math (or add math) so I dont really know what you trying to say but I'll guess. If 9 breaks to 3^3 it is wrong. 3^3=27. Then lets look another way, 9 breaks to 3x3, so you write the equation as (3x3)+(5x2)= you still get 19. Another way is completely wrong but lets say (3x3)(5x2)= you will get 90. I dont know any theory/concept to cross the equation like you shown.
Just bonus,
(3x3)+(5x2)=21
9+10=21
19=21
=21-19
=2 < you still need 2 more :)

I just don't get why people say 9+10=21. They have these weird mathematical proof which if you take a look at it, are completely wrong. I mean, I can prove why 1+1=10 with a bizarre proof. 1=1x1x1x1x1x1x1x1x1x1, so if you add all those 1's up you'll get 10. WTF. Please, people. 9+10 is 19 and will always be 19.
