MathJax
MathJax can be used to render Math formulas. For example, \(a^2 + b ^ 2 = c\).
To enable it, add the following to page.headHtml of YAML configuration or Markdown frontmatter.
page:
headHtml: |
<snippet var="js.mathjax" />Demo
When \(a \ne 0\), there are two solutions to \(ax^2 + bx + c = 0\) and they are $$x = {-b \pm \sqrt{b^2-4ac} \over 2a}.$$
KaTeX
KaTeX can be used as an alternative to MathJax. Just like MathJax, it renders math specified between dollar signs.
To enable it:
