Options for including mathematics on your website include:

• MathJax
• KaTeX
• TikZJax (GitHub, Demo)
• TeXMe
• jqmath
• AsciiMath

The Nift documentation covers how to display $LATEX$ on your websites using MathJax. Repeating the information on this page, using MathJax on your site is as simple as adding the following code to the head of each page:

			<!-- uses MathJax CDN for LaTeX support
				 see https://docs.mathjax.org/en/latest/web/configuration.html for more info -->
			<script id="MathJax-script" async
			        src="https://cdn.jsdelivr.net/npm/mathjax@3/es5/tex-mml-chtml.js">
			</script>
			<script>
				window.MathJax = {
					tex: {
						inlineMath: [['$', '$'], ['\\(', '\\)']],
						displayMath: [['$$', '$$'], ["\\[", "\\]"]],
						processEscapes: true
					}
				};
			</script>
			

You should then be able to paste $LATEX$ equations straight into content files. Both `$..$` and `\(..\)` work for inline equations, and both `$$..$$` and `\[..\]` work for displayed equations (note inside markdown/showdown blocks use `\(..\)` and `\[..\]`, or the `$` syntax). Eg. When $a\ne 0$, there are two solutions to $a{x}^2+bx+c=0$ and they are: $$x=\frac{-b\pm \sqrt{b^2-4ac}}{2a}$$

If you want to insert a dollar sign on a page, as opposed to opening/closing an inline equation, use \$ and MathJax will escape the character.

Note: if you are opening a page locally and are not connected to the internet then MathJax will not load, you will simply see the unprocessed LaTeX equations.
