Reddit reviews Math Smart, 2nd Edition: Get a Grip on Basic Math (Smart Guides)

I agree that Khan Academy is a good resource--another one I always recommend to my students who struggle with math basics is this book. A lot of people are embarrassed by their poor math skills. Unfortunately, there are plenty of bad math teachers and since it builds on itself, you can miss one concept and have trouble with so many other things further down the line. Don't get too down on yourself about it! It's not who you are, it's just one aspect of what you know, and with the right teacher/book/explanation, you can understand it.
