I thought maybe this should go in the Precalc Learning Materials section, but since I can't post there this seems like the next best fit. If I've picked the wrong forum, I apologize in advance. I need a quick review of everything leading up to Calculus. From basic algebra up, essentially (Obviously not TOO basic, like 2x = 4 and such, but still, I want to be thorough). It's been a long time since I've used any of this, but I would like to review it all as quickly as possible in order to take a Calculus class. So my question is: what essential topics do I need to review before taking Calculus? If I were to compile a list for review, what would be the bare bones, structural version? I would like to review all of this as soon as possible, so I'd like to go through all of the absolutely necessary topics first, and then fill in the gaps with any time left over. Links to resources would be great, but not necessary as I can always peruse through the resources forum later. Thanks.
