equation
===============================================================================

%% An `equation` is a block or paragraph level mathematical expression written in LaTeX syntax.


Equations are orefixed with `$$` and can contain any text. They are used to display mathematical expressions or formulas expressed in LaTeX syntax.

For instance,

```
$$ c = \pm\sqrt{a^2 + b^2}
```

when rendered will look like this:

$$ c = \pm\sqrt{a^2 + b^2}

Mechdown also supports inline equations, which begin and conclude with a `$$`. They are expressed with LaTeX syntax, like so: `$$c^2 = a^2 + b^2$$`. This is rendered by a third-party library into $$c^2 = a^2 + b^2$$.
