I wish there was a way I could personally meet Danica McKellar and thank her for what her amazing and easy to understand math books have done for me. I've always felt stupid when it came to mathematics; the kind of mental break I've always had were just debilitating whenever I looked at an equation. Even in college, I'd cry tears of anger and frustration wondering, "What the heck is everyone seeing that I just can't grasp?!" All of that changed when, one year ago, I picked up "MATH DOESN'T SUCK". I am 30 years old now. Believe me, thanks to instructors like Ms. McKellar who truly care that their pupils understand mathematics and make it their own, I finally understand middle school mathematics. I purchased "KISS MY MATH" and waited like a caged animal for "HOT X: ALGEBRA" outside of Barnes & Noble. I feel more confident, excited about this new world I feel has finally opened up to me, all because, like myself, Ms. McKellar is fed up with young girls the world over (especially in the United States) are made to feel that brains depreciates beauty, instead of knowing that the truth is the reverse. BRAVO, Danica McKellar, BRAVO!!! Keep your math books coming!! Should I have a daughter someday, your books will be waiting for her.

I have all three of Danica's books, and I would recommend this to Algebra students everywhere! It's very helpful. I am also excited to hear that she is working on her fourth book, a Geometry one, out August 2!

I just love these books! They are so helpful and filled with great advice. I love the author's message- that being smart doesn't mean being a dork. I would recommend these books to any girl, even if she isn't struggling with math. They are fun to read, and make math concepts easy to understand. I really found some of the tips very helpful. A must read for sure!

This is the second of Danica McKellar's books I am reviewing. The first was Kiss MY Math which I found too crowded to be extremely helpful as a math text book, but acceptable as a reference. The first book I found great as a positive supportive book to encourage academic achievement for girls, especially in math and science. Hot X Algebra Exposed switches to Penguin Publisher. I rarely find a book published by Penguin that I do not find great, even if I am not interested in its subject. This book has all of the extensive girl support features that I liked about Kiss MY Math, but has significantly improved in the specialized and reference book categories. The covers of both books are very similar with the movie star photo and teaser articles that make me think of Seventeen magazine. I am fine with that. Anything that will make a girl pick up this book is great. The format is standard specialized with chapters organized around topics proceeding from more simple to complex. There are catchy (? but not to me) super titles. The index is complete and there are the same graphic feature motifs that allow a reader to locate special type of features by flipping through the book. The big difference with Hot X is that it so much less crowded, with a much less frenetic pace. I actually find her section on Functions and her explanations about whether an equation represents a function or just a relation superior to most text books I have used. I will definitely use this book as a resource for Algebra I and also for Algebra II. The end chapters contain many fresh approaches to tackling word problems. This book will both sit on my lending book shelf for students and another copy will remain for my own use in finding fresh approaches. As a support book for teen girls, it offers lots of support for academic effort especially in math and science, but a lot less of the very young teen stuff about do boys like smart girls. There are lots of true life stories and many serious spots about how uneducated women are more likely to be trapped in abusive marriages because no education means diffculty supporting oneself and children. There are many sections on things such as Confessional: How Can I Focus and Avoid Distractions? This will definitely be a book I use as a resource as a math teacher.

This is a great book for helping students who are afraid of math become confident in math. It gives easy to follow step-by-step instructions and detailed solutions to problems. This book is written with comments that appeal to girls rather than boys, but the author's explanations and solutions can be used in any Algebra I class. The chapters are organized from easy to difficult with each chapter's contents mentioning previously learned concepts. The author then applies these previously learned topics or concepts to new topics/concepts. It's a scaffolding effect, which teachers love to use. The author is highly qualified to write about this topic. This book contains no bibliography.

I am impressed with this math book, I just wished that I would have had something fun like this when I was in school. Although geared towards girls, I am sure boys will be able to learn from her examples and the way that she presents the material inside this book. I haven’t read everything inside the book yet because the book is packed with lots of information and I want to purchase my own copy and add post-its as I go through it, with things I want to refer back to. Inside the book, you will find examples, diagrams, tips and Danica’s own twists on math. She just doesn’t touch on the subjects but she gives lots of examples and she elaborates on these examples. I especially like the language that Danica’s uses in the book, it is plain and simple, yet not slow and lengthy. She explains the math in an easy-to-understand language. As a substitute teacher, I can’t wait to get a copy of this book and get some tips that will help the students in the classroom. Any help that I can find for them will be beneficial. Thanks Danica for giving students the tools to make them successful. Hopefully, this will encourage them and make this subject less of a struggle for them.

I would recommend this to Algebra students everywhere! It's more than helpful, it makes Algebra easy and clears up what the math teacher tried to teach, but failed.

We are very excited to be buying your third book, Hot X. You have such a way with words and keeping things simple yet yielding the optimum result: understanding. We ony wish that you could do a book on Geometry, trigonometry, etc. In other words, keep going!!
