Math

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:
<snippet var="js.mathjax" />
When $$a \ne 0$$, there are two solutions to $$ax^2 + bx + c = 0$$ and they are $$x = {-b \pm \sqrt{b^2-4ac} \over 2a}.$$
