3.1.5, due October 14

This section seems a little more doable, although it is just really hard for me to learn from this book. I think most things will make sense once I get to ask questions and we fill in all the parts that the book leaves out. (by the way, I'm asking more questions in class, I hope this isn't annoying-i know we were getting low on time last class). So it seems like we can use any modulus for the lemmas 3.1.5.1-2, if this is true, that blows my mind. I think this section seems to have the most interesting properties of primes/integers that we have looked at up to this point. I'm having a hard time understanding the notation at the bottom of page 81, if we use this, I'm hoping it is explained as it's introduced.
