### What I Really Wanted to Say is "You Might Need a Better Tutor"

Stu emails me in a huff. "Why did WebAssign mark me wrong on #17? My tutor and I both got 343 for the answer, and WebAssign marked it wrong!"

Not surprisingly, the answer wasn't 343. I did the problem out by hand, and my answer agreed with WebAssign.

I wonder if there are any rich parents of high school students who will pay me $60 an hour to tutor their children. Probably not, as the math tutoring market is flooded with $20 an hour tutors who can't do the problems. A few steady clients and I could buy myself a sock knitting machine.
