Shameless plug. I wrote a library called MathUp with the purpose of having an quick to write and easy to read syntax and compiles to MathML. It is whitespace aware (unlike asciimath) so you can group sub-expressions together in a really readable way. x = -b +- sqrt(-b-4ac) / 2a would actually put the -b ± part in front of the fraction: x = -b+-sqrt(-b-4ac) / 2a works as intended, as does: x = (-b +- sqrt(-b-4ac)) / 2a I haven’t touched it for a minute and it is does not fully support MathML 4, meaning there are expressions which cannot be read properly by chrome. I was always going to revist this at some point but time is hard to find. https://runarberg.github.io/mathup/ https://runarberg.github.io/mathup/
