9+10=21 

A vine that was made with a kid. Go watch it! It's really funny.

Guy: You stupid.
Kid: No I'm not.
Guy: What's 9 + 10?
Kid: 21
Guy: You stupid

Moral: 9+10=21. A great way to be a smart kid. Hahahaha.

9+10=21 

I figured out why
the vine was posted on 9/10/21
he couldnt add
he was asked
whats 9+10
convert date symbols: 9+10=21
so he answered 21
and, i guess, ran away

im tired of this so heres random formula that has it in there and is true
1+2=3*3=9+10=21-((2+2=4)-2)
