11.1-11.2,due 16 November

The most difficult part of the material was the proof for the division algorithm. I did not understand it the first time, but after reading over again it made more sense. Using the algorithm itself was not too difficult to understand.  I think I have been using it since elementary school.

The most interesting part of the material is that we could actually prove something that just seems obvious.  I had never though about trying to prove something so simple, but we need to if we are ever going to use it.
