### 4A and 4B Sections

Has Lavelle done these yet? I feel like he skipped straight to 4C and 4D since I'm trying to do the earlier sections and am having trouble looking for notes on them.

I was having a bit of the same problem where I felt like I wasn't 100% sure how to do the problems. I'm not sure if he briefly went over it in class and I must have not understood it fully or if he is going to go back at a later date. I actually just read the chapter and it explained it pretty well, so I would recommend doing that.
