Query: This book has helped me a lot

I came to this book not remembering how to add a couple of fractions, and now I am able to solve quadratic equations and factor polynomials without too much stress. It's a really good book. It presents information in short doses, then gives a few exercises to do, with the answers listed directly following. I find this a good system, because there's not too much time between absorbing information and making use of it. The examples are nice and clear, and the writing style is basic and to-the-point, without being patronizing waffle.I will take one star off for a couple of typos that were frustrating. For example, presenting a question with a + sign, then giving an answer to a question with a negative sign. There are only a couple of these, fortunately.I'd recommend this to book to anyone that either needs a refresher or is learning from scratch.
