Small-Scale Question Sunday for January 18, 2026

Do you have a dumb question that you're kind of embarrassed to ask in the main thread? Is there something you're just not sure about?

This is your opportunity to ask questions. No question too simple or too silly.

Culture war topics are accepted, and proposals for a better intro post are appreciated.

LaTeX sets hyphens, en dashes, em dashes, minus sings representing negation, and minus signs representing subtraction as five different characters.

Does it use different characters for negation vs subtraction? I thought it was the same character but with different kerning.
