HOw many of you believe? I think they should have the check & correct function that traces back the computation done, and allows to correct.

Would you like it to bubble your answer sheet as well? Only kidding– but seriously, it’s a nice idea. I just usually run the calculation twice (carefully) to be sure. Takes an extra 8 seconds (especially if you use the store and recall buttons on the calculator).
