comment If $xRy$ is equivalent to $xy=1$, what is $R^2$ equivalent to?
i don't understand why xy = 1 and yz = 1 is equivalent to x=/=0 and x=z, we kinda lose information

there exist a x and y such that xy = 1 and a z and y such that zy = 1 if that is the case, then x=z and x =/= 0, and y =/= 0

it's not really a homework question, it's just a theoretical question.
