Learning to solve problems is like learning to play baseball. You learn to throw, to catch, to bat, to run bases, to make plays, and to execute all sorts of refinements of these basic skills. You do not learn to play baseball. You learn these basic skills separately, and you put them together in a new combinations every game. So I repeat: There is no one-two-three method for solving problems. You learn the skills, and you combine them to play the game as circumstances dictate.
