I am in the process of re-learning math to become a high school math teacher. In school I never really tried or studied and would make C's or B's. I have pretty much forgotten everything, and plus I want to learn again from the ground up to better my understanding and how new learners learn etc. So my question is which books do you all recommend that are easy to follow, precise, with the best explanations? So far im aware of the "For Dummies" books, "Practical Algebra", "Effortless Algebra", and "How to Ace Calculus: The Streetwise Guide" Will need to books and materials on all the subjects (algebra 1 & 2, geometry, trigonometry, pre-calculus, and calculus) Thanks in advance for any advice / recommendations.
