Feeling a bit dumb as I plunge into math.stackexchange.com after many years away from the world of mathematics, but can somebody please provide a very quick tutorial -- list of reference pointers would be sufficient -- for getting math markup on math.stackexchange.com. I can use html sup, sub tags, but how to do the more complex markup like fractions, and even drawing diagrams.
Markdown doesn't do much for math, a far as I can tell, but I could be wrong.
Thanks --oldbie/newbie David
metatag, since all questions asked on meta.math.se are expected to be
meta, and added the
textag, since TeX is the system used here to render/display math. $\endgroup$
