Difficult: The most difficult concept for me to understand in this reading is the portion about when sets are denumberable in section 10.2. I think the main thing that I am unsure of regarding denumberable sets is the idea of sets that are infinite. Also, I do not really understand what it means for a set to be denumberable, as in how that affects the set.
Reflective: The easiest section of this reading was 10.1. I thought that this section was easy to understand because it is based on what we already know and understand regarding cardinality. It just shows a new way to figure out if two sets have the same cardinality. Then it introduces the term numerically equivalent sets and defines it as two sets that have the same cardinality. All of it is basic and since I already have an understanding of what cardinality is, it was simple to build on that knowledge.
