Simple function request (altering `max` function)

Question

Currently, using \max{1,2} will print:

max 1,2.

How do I alter it such that it prints:

max{1,2},

without having to use \max{\{1,2\}} in text?

Note: I'm fine with making a new function called \max2 that achieves this (if overwriting the original function is a problem for some reason).

Answer 1

\max does not take an argument so you don't need \max{\{1,2\}} just \max\{1,2\} . However if you want to save yourself those two backslashes

\let\oldmax\max
\def\max#1{\oldmax\{#1\}}
