I love math; at least I want to. I am taking calculus online and it's such a pain in the rear. I should have paid more attention in algebra and pre-calc because I get hung up on little things. I forget to reverse all signs when multiplying by -1 or get stuck on things like factoring or inequalities. I understand quite a bit of what I'm expected to learn, but there might be one step--just that ONE step--that keeps things from clicking in my head so I understand WHY. I have the Calculus Lifesaver, my coursebook and even another calculus coursebook that I refer to, and it seems this isn't even enough. I run into a problem online and I can't find an equivalent anywhere so I can learn step by step. I use the video tutorials and even yahoo answers (sometimes good, mostly just frustrating) and I have even signed up with Mathway. I have seriously considered paying the $60 for a year of step by step, but there is only so much an automated website can solve.
I guess I'm just looking for a place where I can ask a question and understand why I don't understand something, if that makes any sense. I don't want answers (well, I do but that's secondary), but rather the knowledge of how to solve that type of problem.
