Hey all. I have a friend who has been out of high school for quite a while, and he is wanting to learn a little math (just basics). I was wondering if anyone knew where I could find a good book for someone who is not familiar with much math at all. I am guessing we would need to start with things like adding and subtracting integers, then working with fractions, and then into stuff like order of operation, rational expressions etc. Eventually into polynomials, factoring, solving quadratic equations, and maybe some trig. I think this sounds like a fairly standard remedial math/college algebra course at a university. If anyone knows of a good book either for cheap to buy or even free to view online, I'd appreciate it extremely. Thanks in advance!
