Negative Positive
Title: Faulty
Review: Disappointing! At first glance this book does have lots potential in terms of simplifying concepts and formulas, but it is loaded with mistakes - not only in the answer sections, but also regarding some of the methods. I applied their "Method for Finding Square Roots" to numbers other than the given examples, and it did not work. This is not a good buy - even if one merely needs a refresher in math.
