I must say, despite the three stars, I enjoyed this book. I found the various examples of animals 'doing' mathematics very interesting. Also interesting is the section on street math; the fact that poor children in Brazil preform relatively flawless mathematics in their produce stalls, yet fail the same problems on a formal test. However, I was looking forward to something Devlin alluded to in the introduction: a way we can teach math more effectively. However, after all these countless examples, his solution was presented briefly at the final chapter. Essentially, Devlin says that conceptual math, not rote math needs to be emphasized and real life examples should be utilized more. Honestly, I would rather this have been just a fun math book for non-math minded people than have such an obvious ending. With that said, if I could I would give this book 3.5 stars because it is such an interesting read.
