Rest of Section 7.1, Due February 29

Part I: What was the most difficult part of the material for you?

I can understand the part of how a ring is an abelian group under addition, but I think I am still confused on how it doesn't work with multiplication. And since a ring is an abelian group under addition, does that mean that the binary operation is addition and you only need that operation. I guess I am still confused on what a binary operation still means. 

Part II: Write something reflective about the reading. 
 
When they book started taking about a cut out square and rotating it and reflecting it, I thought of the example in class with the Rubik's cube. It is really cool to make that kind of connection and to see how both are groups.
