Section 2.3 - due September 1

First of all, I still think that it is really awesome that Dr. Jenkins has his picture on the front page of a magazine and a whole article about his work. Way to go! Now on to the theoretical processes of numbers - This section was mostly a review of Abstract Algebra again with a few new things.  What I want to know is why these authors insist on saying everything so cryptically.  I have to read through almost every proof at least twice so that I understand what they are doing, even the proofs from Abstract Algebra.  I did think, however, that the use of standard prime factorization to find the GCD and the LCM was probably about the niftiest thing I've seen in awhile. I felt like sitting down and doing a page of computations just for fun. I kind of miss the good ol' computation days. Aaah! Those were the days!
