Buzz: Product Feedback
I was going to build an assessment over slope. I was testing different possible answers and discovered this issue.
Here is the code I used to test answers:
Type: F, Match
1) slope = _____
When I was testing answers the server marked -2/3 correct as expected, but it marks 2/-3 incorrect.
I would expect the answer to be marked correct whether the negative sign is in the numerator or the denominator. I would understand if the answer were 2/3 the server would mark -2/-3 wrong because the answer could still be simplified. But -2/3 and 2/-3 are just different forms of the same answer. There isn't any simplification necessary for either.
I consider this analogous to the expression 2x+3. Even with the setting "Match" the server will also count 3+2x correct.
