Overall I enjoyed this book more than I thought I would and I also found it easier to understand than I thought it would. Nicomachus is always careful to repeat statements and give examples.
The thing that struck me the most about the Introduction to Arithmetic was the elegance of mathematics. The way numbers fit together into patterns is really amazing… and none of it is man-made. The patterns are inherent! It’s darn good evidence for an ordered, lawful universe. It was interesting how Nicomachus sometimes took a “mystical” (for lack of a better word) approach to mathematics. It seems strange coming from what is basically from a math textbook, but given the inherent elegance of mathematics, it’s easy to see why he would.
I've disliked math from an early age (and have struggled with it due to my math block i.e. my inability to calculate in my head), but I remember having one teacher in Grade 11 who actually made math interesting for me. Like Nicomachus, he emphasized the patterns and elegance of math. Nicomachus brought me back to that interest.
