In a task, most fields have the option to add math or chemistry notation via a LaTeX/MathML editor (under the Σ Sigma symbol).

# How to add equations or symbols to a task

To add your math notation, put your cursor where you want the notation to appear and select** Σ **to open a math editor with some of the common notations needed.

To enter your math, simply add the parts you need by using the relevant buttons.

Then use **Ok **to save.

You’ll see your math elements shown with a dotted line.

You can re-edit a math element by double-clicking within the dotted field.

# How to use the math editor

Entering math notation can be a little more complex than text we have a video and some tips to help.

**Note: **Although this video is for learners, the options for an author are very similar (you just have access to a few more options).

## Tips for using the math editor

You can save time by using the keyboard tips like * for times, / for fraction, and ^ for "to the power of".

If you're after something a little more complex, you can select View Source and add in your LaTeX (or MathML) as you usually would in a text element. See How to format maths and chemistry formulas with LaTeX for more detail.

Make sure your cursor is at the top of your screen when you open the editor so you can see the entire window.

Sometimes the editor can take a little longer than other things to load, if you're worried something has gone wrong, give it a few seconds more and it will probably load.
