Don't listen to anyone here that even mentions Khan Academy. It's good if you don't mind wasting a lot of time (I'm assuming you're a remedial learner). You need two components to properly learning math: a) theory b) practice # THEORY Sequence: 1) Algebra 2) Geometry 3) Trigonometry 4) Calculus (single, multivar calculus) Here's links for (1)––(3) http://www.mathsisfun.com/algebra/ http://www.mathsisfun.com/algebra/ http://www.mathsisfun.com/algebra/index-2.html http://www.mathsisfun.com/algebra/index-2.html http://www.mathsisfun.com/geometry/ http://www.mathsisfun.com/geometry/ http://www.mathsisfun.com/algebra/trigonometry.html http://www.mathsisfun.com/algebra/trigonometry.html For calculus, I don't know anymore productive way than taking classes at a local Junior College. You need to place into these classes since you haven't taken math classes in a few years. Try to place into a compact summer class. My local college lets me place into Calc 1 & 2 (Honors) as the highest class to place into. The website (mathisfun) is a great resource. It looks really kiddy, but concept are explained properly. If you can get over the visual aesthetic, you can relearn mathematical ideas quickly. # PRACTICE Buy a book. Preferably a book that has a boat load of problems for you to run through. Build confidence through exercises.
