MathJax is a simple, yet powerful, way of including Tex/LaTex/MathML based mathematics in HTML webpages.

## Usage

To enable MathJax support configure your _config.xml to:

• Set kramdown as the Markdown parser.
• Enable MathJax.

The version of MathJax enabled is v3.

An example setting for _config.xml is shown below:

markdown: kramdown
mathjax:
enable: true
combo: "tex-svg"
tags: "ams"


Use  as delimiters to enable TeX math mode, both for inline and display (i.e. block) rendering.

Here is an example equation that is inline: $$a^2 + b^2 = c^2$$, where $$a$$, $$b$$, and $$c$$ are variables.

Here is a block rendering with no default equation numbering:

$\frac{1}{n^{2}}$

And, below is a block using the and LaTeX delimiters. This equation will be numbered in the ams and all setting for mathjax.tags.

$$$\mathbf{X}_{n,p} = \mathbf{A}_{n,k} \mathbf{B}_{k,p} \label{test}$$$

If equation numbering is turned on, we should see an equation number here: $$\eqref{test}$$.

An example using the {align} LaTeX environment is below. The first equation has a \notag directive.

\begin{align} (x + y) (x - y) &= x^2 + xy - xy + y^2 \notag \\ &= x^2 - y^2 \end{align}
