I’m creating an activity on multiplying and dividing rational expressions. I am using a hidden graph to generate the question and calculate what the answer should be because I want my students to simplify fractions. This works perfectly when both fractions are just numbers. But now I am on a type of problem where the numerator of one fraction will be the variable x. I have been parsing the user input so I can compare it to what the value should be that I’m calculating on my graph. But now, when I get the numerator, I want it to be a string value since they are typing something like 12x as the numerator. Is this possible?
