Ask HN: Can math books help you become good at problem solving in general?

Problems can have mathematical nature or a non-mathematical nature.

By problem solving I understand:

1. Understand what the problem demands

2. Find out edge/special cases

3. Work out examples

4. Devise a solution to the problem.

I am not implying merely reading a book will make you a problem solver. Problem solving will make you good at problem solving.

Have you come across any book that helped you become good at problem solving?
