 Pro I can prove 9+10=21Report this Argument Con Im using Casio 570 calculator, google calculator, my pc calculator and my old abacus I still get 19.Report this Argument Pro 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.Report this Argument Con 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 :)Report this Argument

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.
