Moodle: Maths and Moodle

You may not have realised that Moodle has a built-in TeX filter that allows you to display mathematical notation. Simply surround your TeX code with double dollar signs. For example:

$$\int{\frac{1}{x}}dx=\ln|x|+C$$

is displayed as:

$\int{\frac{1}{x}}dx=\ln|x|+C$

This works in any of Moodle's HTML editors, so you can add maths:

when composing a web page,
in quiz questions, reponses and feedbacks,
in assignment instructions,
in forum posts,
... and many other places.

Note: if you actually want to show two adjacent dollar signs, use three of them!
