3.6, due October 28

This section seems relatively more doable than some of the other sections we have been doing lately. First of all, we have already used some of these things like multiplicative functions and we already knew what that means. One thing that was a little bit frustrating is that we were expected to be recalling the Mobius function , but luckily it's not too complicated. I do think it will be SUPER helpful to hear it explained out loud though. What does really confuse me is the inversion formula. I think what's complicated about it for me is combining so many things from different contexts.
