I’ve enabled support for something called MathJax, “a JavaScript display engine for mathematics that works in all browsers.”

On the previous version of the forums, there were times when science-minded members would try to share or explain formulae, but that’s not the easiest thing to do in a text editor. Now, all your mathematical dreams can become reality.

To use this, wrap your TeX or LaTeX formatted math in **$** (for inline use) or **$$** (for multi-line use).

For example, this:

```
When $a \ne 0$, there are two solutions to \(ax^2 + bx + c = 0\) and they are:
$$
x = {-b \pm \sqrt{b^2-4ac} \over 2a}.
$$
```

Will result in this:

When a \ne 0, there are two solutions to (ax^2 + bx + c = 0) and they are:

x = {-b \pm \sqrt{b^2-4ac} \over 2a}.

If you’re unfamiliar with the TeX format and would like to use this feature, take a look at Moodle’s documentation here:
