Can I create a quiz using mathematical formulas?

Yes. If you write a formula in Latex format between [#and#], it will be converted to an image and displayed in the question.

You can also use it in the commentary.

e.g.)
What is the sum of the internal angles of a pentagon?
sa:
[#540^\circ#]
[#360^\circ#]
[#450^\circ #]

You can also check the display example of formula input in Latex format from the following site.
