Review title: Poorly done
Product review: I was looking for a book that would help me brush up on my financial math and this does not do the job. Day does a poor job of explaining the material, and furthermore, his CD is poorly done. He does not enter most of the formulas, but rather he hard coats his numbers. This makes it just about impossible to follow what he is talking about in his book as the reader must somehow come up with the formulas that he is describing on his own. Day does a great job of protecting his models from being copied as no one would want to recreate the formulas he is using, but in doing so, he prevents the reader from learning. If you are looking for a good book on financial mathematics, this is not it.
