Now, I learnt maths a long time ago, but I want to learn it again (kinda self-teach), mainly for computer science. I know quite a lot of arithmetic and basic geometry. I understand about exponents and logarithms. However, I would love to learn more algebra and equations.
I want to learn more about Algebra, even if it involves starting again. I've checked out KhanAcademy's Pre-Algebra and Algebra course. My question is
With my knowledge, would the Pre-Algebra tutorial help me understand most about what is taught in the Algebra tutorial?
How long is an estimate for me to learn?
Should I start with early maths before touching it? I do know maths.
I may also want to learn Linear Algebra. I might even use the lectures done by Gilbert Strang from MIT Courseware, which I've found as a recommendation on several sites. It looks quite interesting.
