A7 mistake
I goofed. Period 1 received a much longer assignment for A7 than my even classes because I didn't photocopy the entire thing. There are 15 problems that everyone got, then the numbering restarts and the additional set has 12 more.
The pdf of the assignment on my website is now correct, and also now has a solution guide. I will only collect the first 15 problems as homework. Do the remaining 12 because they're good for you, not because you have to! (In other words do them if you think they'll better prepare you for the quiz.)
