[latexrefman] \bigtriangleup appears to be a binary operator

[Masato Shinokawa]

Hello,

I was looking for a way to typeset symmetric difference A △ B and found
\bigtriangleup on 16.2 Math symbols <https://latexref.xyz/Math-symbols.html>
.

This document says it is an operator, but it looks like a binary operator.

Does this mean that \bigtriangleup is actually a binary operator?

The same applies to \bigtriangledown as well.

Thank you,

Masato
