Section 7.6, first part, due March 23

What was most difficult?
The most difficult part of this section was focusing! I'm finishing my preparations for the exam, so it's hard to be thinking of new material. I thought it would be difficult to deal with right and left cosets for these subgroups, but once I read the examples after the definition of normal subgroups, it seems pretty straightforward and manageable.

Reflection
The best thing about this section, was that it cleared up cosets for me. For some reason, I was struggling in the last section with the assignment. Using the definition as exactly as I thought it was written, I kept getting the wrong idea for cosets. This section made it totally clear.
