Should it be "\textminus" instead? I never used it but my expectation
that it was added for text mode outside of equations: \minus1. It
required \usepackage{textcomp} in the past, but it seems it is not the
issue any more, so the symbol is available out of the box. I was not
following that changes in LaTeX so I may miss something.
\textminus appears to work without textcomp. However, I am not sure if it
should be used instead of math version.
Timothy tried texlive-2022, I had 2019 installed, users of old versions
may add \usepackage{textcomp}.
Look at the attached screenshot where I tried to compare how \textminus
vs. $-$ would look inside a document. I find the math version to be more
visually appealing. Of course, we can always change to \textminus if
people more familiar with typography jump in and ask for the change.
I am a bit lazy to check what font and what codepoint is used in each case.
From my point of view, the correct way to type negative numbers is
\(-1\), not \(-\)1. TeX math mode sets proper spaces around the
character, e.g. \(1 - 1\) has larger spaces around. I considered \minus
as something special for cases when a user has reasons to avoid math,
e.g. to avoid MathJax or images when a document contains only a few of
simple expressions.
