Read: Read up through beginning of Section 3.4.
Turn in: 3.54, 3.58, 3.59
- For 3.54, you can just reference Fact 3.47 for many of the field axioms for \(\mathbb{Z}_n\), and if you want a hint about multiplicative inverses, see the back of the book.
- You’ll want to use 3.56 to prove 3.59
Extra practice: 3.52, 3.57
