Section 8

1. The modulo concept did not make a lot of sense to me. In the Python lab I learned that modulus just means taking the remainder after division as the answer, but I did not grasp how this was working in the reading or how it was being computed. Once someone else explains it to me in English I will probably understand it better.

2. The definition of absolute values seems critical in these proofs. I already knew what absolute value meant, but it now has a deeper meaning seeing how I can use the equation |x|=-x for all x<0. using this in both directions will help with many proofs in the future.

Midterm Review 10/2/18

I think the most important topic we have studied have been how to outline and write proofs. They are simple enough for the most part, but they have helped me to think more deeply about topics that I have understood but maybe not understood fully, and they have also helped me to think more abstractly to understand things that I haven't understood before. On the exam, I'm mostly expecting to see proofs and set theory questions. I think there will be a few logic questions but they will mostly be tied up in set problems and in formal proofs. I would like to see a few more examples of rationality proofs, like the ones from homework 11 and 10. Those were a bit harder for me to understand the theory behind the proof so seeing those written out would help me out a lot.

sec 28

this section wasnt terrible, I understood what was going on for the most part. It is a little more abstract since we are dealing with infinite sets. I also didn't really know what the new notation was for, the squiggly N symbol was very weird looking. I think it just need to hear it explained out loud to fully understand it.

12/7/18 midterm review

The most important thing that we have studied since the last midterm has probably been Schroder-Bernstein theorem and cardinality proofs. They are a little bit abstract since we are dealing with the size of infinite sets, and my intuition gets broken from time to time, but so many proofs and theorems build off of them. I also think that the limit proofs we did are very important, because it is the basis for Calculus and analysis which is what I will be doing next semester and in the coming semesters. For the midterm I am expecting to see cardinality proofs for the proof section, and for the multiple choice and true/false some basic questions about cardinality and limits. I'm a bit more concerned about cardinality proofs because that section was the hardest for me, so if you could go over some of the more difficult cardinality proofs tomorrow that would be great.
