By the way, it’s not just in math that this happens. In law school and on the bar exam, we were told that it didn’t matter whether we got the “right” answer; they were interested in our thought processes and how we got there. In practice, guess how many times a client walked in and said, “I don’t care if we win this lawsuit (if you negotiate a good deal, etc.); I just want to know that your thought processes were good”?</p>
