## 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 wont parse as math. If for some
reason you need to enclose text in literal $ characters, backslash-escape them and
they wont be treated as math delimiters.
```
