Clear and generally effective, but never particularly invigorating in its claims; for better and worse, very chatty. I like math (NERD!), and would have liked a bit more of a challenge (see David Foster Wallace's Everything and More
). But it's more fun than any 36 of 40 math teachers, so what the hell.
That's right, math teachers. I'm throwing down. Push the taped glasses up your nose, square away the sleeves on your stained-white button-downs, hide the pointy edge of your compasses, and get ready to rumble.
