What does this question reveal about the student’s understanding?
(Also: do you agree with the mark given by the teacher?)
What’s up with the above? Say something smart in the comments about the implications of a mistake like this one. What’s another mistake that you would expect this student to make in the future? What’s a mistake that you wouldn’t expect the student to make?
Thanks to Jonathan Newman for the submission.
