Khanacademy seems useful. Thanks! As for practical maths, aren't there several books intended for engineers that deals for just this? As I'm planning mainly to excel the mathematics course next year; what about the oldschool rigorous approach of hardcore study(sitting with your nose in a book for hours?)? I simply want to be prepared for what they are going to present, which is essentially all the basic subtopics. What I had in mind was something(instruction material) that would present a concept, give a brief discussion(the books we use fail to explain the concepts, they simply give guidelines, but doesn't say "why" or "how". But again, it might be my brain failing me or because I forgot the preliminary rudiments) on it and then some exercises or whatever. Kind of like Serge Langs book that I mentioned, but more basic. Is this a bad approach? I'll check out those "Demystified" and "Teach yourself" books too. Thanks

Yes, we have done much more than simply what I described first. But much of this information has faded away from my memory. We have gone through all major subtopics I believe, basic geometry, percentages, fractions, probability theory, statistics, graphs, etc. but I can't remember any of the formulas. The only thing I can remember off the top of my head are the concepts of addition, division, multiplication, subtraction, some basic percentage formulas, basic geometry and some more. With some thinking I can probably fish out something more I remember, but right now were not studying mathematics in school for the course I'm taking(for what I'm educating myself to) so not much of this is fresh in my mind. I intend to become a construction engineer, so that's what its for. Aside from that, I also want to get to know some physics, and for the freedom simply knowing stuff I guess. Edit: The math that I'll attend to soon(next school year) will be very hard because the education system takes for granted that I know the basic concepts that I've now forgotten. This was one of the reasons I tried to do some extra work at home.

I'm a school student*; and like many other school students, I have a hard time with mathematics. I figured I'd do some extra work at home so I bought and tried out Langs "Basic Mathematics"; which is, as the title implies, basic. But I had a hard time following it from the first or second chapter so I quit. It was probably too advanced, so can anyone give me tips of literature that gives the absolute basics? I know the concepts of addition, subtraction, dividing and stuff you learn since you're a little kid, but after that things start to get blurry. I assume that the school system takes our knowledge of previously covered concepts for granted. But honestly, I forget most things we do in school after a few days so I have a hard time comprehending the stuff we're "learning(supposed to be, at least)" as I have no grasp for other concepts that need to be understood first(I have no idea though, I might just be stupid). Anyway, I figured I'd learn it "for real" now, with an actual understanding of all the concepts. But I need some guidelines. Any tips? *(not relevant)I'm studying in Sweden and I am currently in the "gymnasium"(16 to 18 year olds mostly), which is the stage before university. Thanks.
