comment having trouble with this well known fact $ab | a^2 + b^2 +1 =>a^2 + b^2 +1 = 3ab $
no it worked out by itself, i just waited a minute or two, probably because the latex was compiling, or because I use and experimental version of Firefox. I registered on the site, its very helpful, just what I was looking for. Thank you very much.

comment Why is antisymmetry necessary for comparison sort?
I think sorting would go fine, but data structures like set and map wont work, because without antisymmetry, you cant find the element in the set, it could be anywhere.

This definition of antisymmetric refers to numbers $x, y$, not objects

If I'm at least as old as you, and you're at least as old as me, we are the same age.

Your relation "is at least as old as" is antisymmetric.
