Buzz: Questions & Answers

Comma character and equation editor

I am working on an assessment (Course ID# 159412198 Activity 9cd7ae2512b24045bb14fe8c239f2712) and have a question. I am using variables to generate different numbers so that the students get unique questions. Because I am using variables and need to use the eval() function, I have to use one of the mathematical options for the question type. Some of the answers include more than one answer, i.e. intercepts at 0 and 3. I would like to have the students separate their answers by a comma and list them from least to greatest. Unfortunately, from my testing, a comma is not an acceptable character when using the math expression question type options. Here is a screenshot of what happens when I use a comma with the math expression - equivalent option: Screen Shot 2021-05-25 at 10.37.51 AM.png It seems that the individual answers are acceptable but the question is marked incorrect. I tested my theory and changed the comma to a + because it is a character that is on the equation editor that can be accessed by students. Screen Shot 2021-05-25 at 10.38.50 AM.png As you can see, the answers were accepted and the question was marked correct. There are no symbols that are currently appropriate for this type of separation. I would prefer to avoid multiple blanks as not all the questions have multiple intercepts and I do not want to tip the students off as to how many answers they should be seeking. I am wondering if there is a way to get the comma as acceptable character type or to get the question to mark as correct. I am attaching a screenshot below. Thanks! Matney
