1. I did not understand the proof of Theorem 7.8 on page 177 - maybe it is because I need to understand finite order better first. Hopefully we go over this more in class!
2. I am glad I took liear algebra before taking this class. There seems to be a lot of applications from it. For example, in Corrolary 7.6 there is an important distinguising feature between Abelian and non-Abelian groups: (ab)(-1) = b(-1)a(-1) and not always a(-1)b(-1). Like with matrix multiplication, (ab)(-1) = b(-1)a(-1) also.
