Why do math teacher's give kids around 100 easy math equations? It pisses me off. The average person in my class will be like "**** this I'm doing this at home" and then start talking to friends.
Couldn't tell you. I know that once you get to college, it will generally be something like, "Problems 5 through 30 deal with the material we just covered. It's not mandatory, but doing the problems will really improve your understanding of this concept."
