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 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.
