Any Dopers have a recommendation for me? I would like to get a book or series of books that would cover the math/algebra or whatever that is taught from grade school up to and including high school. I don’t know algebra from pre-calc from linear equations. Back when I was in grade and high school, everyone still used Roman numerals, and long division hadn’t been invented. Any suggestions?
For something to read on your own, I’d suggest the series Algebra The Easy Way, Trigonometry The Easy Way, and Calculus The Easy Way, all by Downing, IIRC. These are not textbooks in the sense that we are used to; they are written in a science fiction style. I believe they are all still available at bookstores (usually in the reference section, near test-preparation guides).
