to be fair, you'd get marked off for getting ln(1) wrong, so I think we have to give credit for getting it right. (grading on a scale solves that problem, though i guess the gaussian hadn't been invented yet). the numerator is also "wrong"; of his 3 errors, 2 of them are wrong only "off by one" in the last digit, same direction both times, so without understanding the rounding rules in effect it's hard to know whether what happened is an actual error. ln(7) is a mess though but still at the least significant end.
