MathJax is an open-source JavaScript display engine for LaTeX, MathML, and AsciiMath notation that works in all modern browsers.
MathJax uses web-based fonts to produce high-quality typesetting that scales and prints at full resolution, unlike mathematics included as bitmapped images. With MathJax, mathematics is text-based rather than image-based, and so it is available for search engines, meaning that your equations can be searchable, just like the text of your pages.
Latex Syntax
I'll show the "ascii math" and then the $-wrapped version (which is the Obsidian syntax to show it via mathjax
For inline, the $ has to be touching the characters. I.e.,
