How can I put a math equation or math symbols in the answer choices? I can get them in the body of the question but not the answer choices.

I'm creating a math quiz and can get equations and math symbols in the body of the question, but I can't figure out how to put equations or math symbols in the answer choices, using fill in the blank question.  I was trying to put in the infinity symbol and can't figure it out.
