AsciiMath VS GitHub Flavored Markdown

Sure thing, a quick search yields Asciimath which seems at least at first glance as huge improvement in the syntax department: http://asciimath.org As for LaTeX in general, Markdown beats it soundly in most aspects. - Source: Hacker News / about 1 year ago

What are the syntax differences to https://asciimath.org? - Source: Hacker News / over 1 year ago

I did some Googling, and thought AsciiMath is the answer (simply because it also contains "Ascii" in the name). Turns out it's a different solution. Source: over 1 year ago

Math syntax is a bit more challenging, because I'm sure no one wants 12 even if that would make the grammar simpler. Attempts to do this are thin on the ground: as you note, Markdown and other similar tools completely punted on math. AsciiMath is one idea, although not what you want in a full-fledged typesetting language. Source: almost 2 years ago

I like to use asciimath for this, though I realize that it's not as powerful as LaTeX or MathJax. There's a decent Rust port: asciimath-rs. Source: almost 2 years ago

Not sure quite what you mean. Are you asking "what should I put on GitHub" or "how to make it look pretty?" For the latter, check out https://docs.github.com/en/get-started/writing-on-github. Source: about 1 year ago
