Title: I was disappointed
Review: I bought the book because of all the positive reviews; I did read the negative reviews, but decided to take my chance.This book is useful for reviewing materials that you have learned in the past but forgotten. In my opinion, it's not that good for beginners of mathematical finance (who wants to learn it seriously) because the presentation is so unclear, with lots of hand-waving and skipping essential steps. I am a beginner myself, and I would rather struggle through more mathematically difficult but clearly presented textbooks.I wanted to give this book one star because it was way below expectation, but I gave it two because at least it attempts to offer a layman's explanations (not a very successful attempt, but a positive thing, nonetheless) behind all the math. And it's not like I gained absolutely nothing from it. I guess I would recommend giving this book a shot if you could get it cheaply, perhaps a secondhand copy.
