The question surely could have been answered with the error in it. However, the problem was in the fact that when the exam proctor alerted all of us as to the problem, no further instruction was given on how to handle the error in the event that students already answered. The lack of instruction caused students to react differently (This was about an hour into the exam). Some, including myself, re-worked the problem; which in turn screwed us over with regard to the amount of time left for the last question. Others did nothing. I guess the Dean thought it would be unfair to penalize those who left the first question uncorrected and had the "wrong" answer - just as it would have been unfair to penalize those of us who corrected the first answer, but were unable to fully answer the last question.
