Render Math With Mathjax

## Mathjax Math equations can be rendered using [Mathjax](https://www.mathjax.org) syntax with AMS symbol support. Optionally enable this on a per-page basis by adding `mathjax: true` to your frontmatter. Then, use `$$ ... $$` on a line by itself to render a block equation: $$ | Pr*{x \leftarrow P*{1}} [A(x) = 1] - Pr*{x \leftarrow P*{2}} [A(x) = 1] | < \text{negligible} $$ The raw version is: ``` $$ | Pr_{x \leftarrow P_{1}} [A(x) = 1] - Pr_{x \leftarrow P_{2}} [A(x) = 1] | < \text{negligible} $$ ``` Write in-line equations with `\\( ... \\)` , like \\( x^n / y \\) . It's easy! ``` Write in-line equations with `\\( ... \\)` , like \\( x^n / y \\) . It's easy! ```
