When I found this book online, I couldn't believe my luck! I am currently enrolled in a quantitative literacy class and this book is the text we are studying from. Math is not my strong suit and so far this book has helped me. It explains quite a lot and has formulas to support what it's teaching. It teaches logic and problem solving, quantitative info for everyday life, probability and statistics, modeling, and how math works in art and music, and how it works in politics. This is the fifth edition and the one I needed for my class and I have not been disappointed with it.
