When editing text in Moodle you can type in mathematics and scientific notations and formulae using the equation editor.

TeX (**/'tɛx/tekh**, often pronounced TeK in English) is a very widespread and popular way of representing Mathematics notation using only characters that you can type on a keyboard (see Wikipedia). This makes it a useful format to use in Moodle since it can be entered anywhere you can type text, from forum posts to quiz questions.

TeX expressions can be entered in multiple ways:

- typing them directly into texts.
- using the Java-based Dragmath editor in Moodle's TinyMCE editor.
- using the HTML-based equation editor in Moodle's Atto editor (since Moodle 2.7).

Afterwards, TeX expressions are rendered into Mathematics notation:

Anyone editing in Moodle using the text editors can insert equations.

Make sure Java is up to date on your computer.

- Have the default Moodle editor enabled (in case of doubt, its name is Atto).
- In your Moodle space, be in a context where you can edit (e.g. a Page, Quiz question, Forum post).
- In the text, editor toolbar select the Insert Equation button; either the equation editor will display or you will be prompted to allow it in your browser's security settings (if the latter, then do allow it).
- The Equation Editor should now display.

As you enter TeX equations you can see these appear in the preview at the bottom of the window.

You access the equation editor from the Moodle text editor's equation button - you may need to toggle on the full view 'Toolbar toggle' button (the top-left button) to see the equation editor button.

Further help

Further guidance on Using TeX Notation is available from moodledocs.

If you find any inaccurate or missing information you can even update this yourself (it's a communal wiki).

If you have a specific question about the tool please contact the Digital Education team.

Make sure you have Java up to date on your computer.
