“Some say 2+2=4. Others we’ve spoken to believe the answer is 5.”

I say 2+2=1. Proof me wrong!

(and I'll proof you that Z/3Z is a ring).

@13reak @aral
Idk what the second bit means, but I’m interested.

The first bit *could* be true if weird geometry or or something

@MxVerda @aral

Z/3Z is the ring of natural numbers (Z) "modulo 3". I never thought I'd need that again  

So essentially (2+2) mod 3 = 1.
