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: almost 2 years 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
