Thanks for the link, I skimmed through the Direct Proof PDF - it seems very complicated. I have done some Discrete Math which I found fairly understandable once

  One of the things that I used to do with knew math ideas was to write a program that illustrates them, then tweak values in the program to get a better intuitive feel for how the math works. I usually come to understand the concept through experimentation that way, and from that point the actual notation doesn't matter as much (although it's still like reading a foreign language, to a certain degree).
