what if equality wasn't reflexive, like 3=3, but not 1+2=1+2, because 1+2=3 but not 3=1+2.

@ClarkHat@ValueOfType Equality is always symmetric -- ie if 3 = 1+2 then 1+2 = 3 -- but it needn't be true that 1+2 = 2+1 (commutativity)..2 replies 0 retweets 0 likes

@ValueOfType Sometimes indicated with an arrow, although that clashes with standard homological-algebra-style notation.
