Is there a way to mark a question correct if it just contains a certain value? For example, I want to mark it correct if a student puts the value 17 into the input, regardless of what else is with it, so I don’t have to include every possible “correct answer”. I want it to be correct if they write:
17
<ABC=17
< A B C = 17
<ABC=17 degrees
and so on.

I know I can instruct the students to “just type the number in” but I’m just wondering if there’s a way to do this without that instruction

If you have not used it before, it checks the latex for the number as a whole, not it’s digits. So, any of your samples would be true, but “17.1 degrees” would not be correct.
