I looked at the division problem and guessed 472, and got it right. I think guessing accurately is important. You almost never have time to work things out. The 4 was obvious, and the 2 was probable--they wouldn't likely require a remainder from people. And so that left the 7 to guess. I mean, given a set of problems requiring such division, most could be acceptably answered by nearly-correct answers. This isn't true in finance, but for most other things it is.
