It covers basic techniques for solving a problem, from “solve a simpler problem” to “decompose the problem into subproblems”. Its examples are high school trigonometric exercises, but the techniques apply much more widely.
I claim that if you understand the lessons in this book (which, granted, takes a lot of practice you will need to get elsewhere) you get 60% of the benefit of having coursed a math major.
I would recommend everyone to read the book How to solve it, by Polya.
