2.1, due January 10

In this reading the most challenging thing was to train my brain to think about congruence in the right way.  I kept trying to read 17=5(mod6) as 5 divides 17-6.  Once I was able to get the true meaning of that expression down the rest came fairly easily.  A small hiccup came when I got to congruence classes, but after reviewing the definition and several examples that too became clear.  When I started reading this section, I was a little excited because I remembered liking our discussion of modular arithmetic in MATH290.  I was a little rusty after a year's absence but it's slowly starting to come back.  It might sound weird but I like congruence classes.  I find them fascinating!
