+
+[Commit](https://github.com/wekan/wekan/commit/82fa632197a0e3b88d26c557f1dc8cc18b05b18b).
+
+## Examples
+
+[Examples From NPM package](https://www.npmjs.com/package/markdown-it-mathjax3)
+
+**Inline**
+
+Surround your LaTeX with a single $ on each side for inline rendering.
+
+`$\sqrt{3x-1}+(1+x)^2$`
+
+**Block**
+
+Use two ($$) for block rendering. This mode uses bigger symbols and centers the result.
+```
+$$\begin{array}{c}
+
+\nabla \times \vec{\mathbf{B}} -\, \frac1c\, \frac{\partial\vec{\mathbf{E}}}{\partial t} &
+= \frac{4\pi}{c}\vec{\mathbf{j}}    \nabla \cdot \vec{\mathbf{E}} & = 4 \pi \rho \\
+
+\nabla \times \vec{\mathbf{E}}\, +\, \frac1c\, \frac{\partial\vec{\mathbf{B}}}{\partial t} & = \vec{\mathbf{0}} \\
+
+\nabla \cdot \vec{\mathbf{B}} & = 0
+
+\end{array}$$
+```
+## Syntax
+
+Math parsing in markdown is designed to agree with the conventions set by pandoc:
+```
+Anything between two $ characters will be treated as TeX math. The opening $ must
+have a non-space character immediately to its right, while the closing $ must
+have a non-space character immediately to its left, and must not be followed
+immediately by a digit. Thus, $20,000 and $30,000 won’t parse as math. If for some
+reason you need to enclose text in literal $ characters, backslash-escape them and
+they won’t be treated as math delimiters.
