What are the underscore operators here? I'm curious, this may be an established convention but I have not seen it before

- stygiansonic 10y agoI presume they are placeholders to represent any binary operator, i.e. +, -, etc. The operator should be the same in all the placeholders or have the same precedence for the two expressions to be equivalent.

- nightcracker 10y agoThey are just arbitrary placeholders for any operator.
