I want to get good at math, any good book suggestions? [closed]
I'd suggest that you look seriously into the Khan Academy. The link will take you to a page that lists all the math tutorials available on the site, topics covered, etc. For many of the topics covered, there are exercises you can do, and ways of measuring your progress.
The leader of the Khan academy is likeable, approachable, and the "leading" star in the videos, well respected for his "down to earth" approach.
I really think this site can help you out! It covers everything one hopes to understand from high school math, and more!
You might also want to read What is Mathematics? by Courant, Robbins, and Stewart. You can preview the book at the given link. It's a readable book, and helps many overcome their conviction that they are "not good at math".
As an aside:
Two of the sins of the rote arithmetics and rote-math, as taught in school, are the notions they instill that
1) every problem has a definite answer, (also usually conveyed: "there's only one right way to find the answer/solve a problem),
2) that you should be able to come up with that answer instantly or you're stupid.
Both are wrong.
The book Thinking Mathematically dispels these myths and presents a better way to learn mathematics and to think mathematically. However, note that learning how to learn mathematics from a book is a challenge. It is easy to miss the point, for instance by not doing the exercises. The Khan Academy videos will help to "model" mathematical thinking and problem-solving. But Math is not a "spectator sport"; it requires active participation in and ownership of your learning and education.
The classic book reference is probably Polya's "How to solve it". Maybe have a look at it.
The Khan Academy as mentioned above is a great recommendation.
In that you specifically mentioned algebra, you might consider Gelfand's "Algebra."
http://www.amazon.com/Algebra-Israel-M-Gelfand/dp/0817636773
It is a work by a real master of mathematics, yet presenting the topic at a level you can understand - giving you tremendous insights into algebra, and how to think in terms of math in general.
