Hi Betty!

In the Match it widget, you can use images (possibly screenshots of your equations) :

For the MCQ  you can also use images if you need to put equations in the possible answers:

If you need to put an equation in the question, you can use Text widget to create the question, then in the actual quiz widget, leave the Question box empty.

If you have any further questions, you can send us an email to support@openlearning.com.

Thanks!
