I read these in 5th grade or so and learned most of middle school and high school math just from those.
They're written as a fantasy novel in which the characters discover the relevant math concepts as part of the story. I know, you're thinking that's a silly gimmick and it can't possibly be any good, but it was actually done quite well. At least until the later parts of Calculus where the situations have to get pretty contrived.
Highly recommended, at least for precocious kids who like math and fantasy novels.
When I was in HS, I wish my school had used books like Serge Lang's or even Gelfand instead the terrible textbooks we were forced to use. I ended up needing to use Saxon Math to review, which was better because it always builds on previous skills instead of moving on to the next topic and never revisiting what you've already learned again.
I really hoped the trig book would help me get over my mental block, but it still didn’t work. There’s something about Trigonometry that just befuddles me.
Have you seen the animation about how sin/cos/tangent are derived? I was absolutely befuddled by trig although I was able to do it by learning rules, until I saw that thing.
