We had a quiz tonight in math. The instructor didn’t put any of the hard problems on it. There were 12 questions. I worked all of them and checked all my answers in 15 minutes. The answer to one of them was the empty set, which delighted me for some reason. I think I liked the fact that I understood what I was doing well enough to be certain there was no correct answer to the problem. I think I understood what I was doing, anyway. He’s going to return the quizzes on Sunday. We’ll see how I did.
The new material this evening covered absolute values, which are kind of intriguing. Imaginary numbers still fascinate me more than anything else we’ve gone over, but absolute values are kind of fun to play with.
Math is interesting. Why did I hate it so much when I was a kid?
