Hi, I'm writing a quiz and I'd like the students to submit comma separated questions.  For example, a rectangle has an area of six inches and the long side is one inch longer than the short side.   What are the lengths of the sides?

 

I'd like them to submit something like 

3,2

I can't figure it out.
