16.4, due on December 7

• The only thing I found a little bit difficult was the addition of points in a field on an elliptic curve. I followed what was said in the book, but it is still a little bit unclear how to do it.
  
• This section of reading was really neat because it brought back fields and presented a new approach to using them. I didn't understand fields at first, but after receiving some help and explanation I really feel like I've got them. It was nice to be able to take a relatively new concept and apply it to a relatively old one. Putting the two together helped my understanding of fields as well as my understanding of elliptic curves.
