“For all the time schools devote to the teaching of mathematics, very little (if any) is spent trying to
convey just what the subject is about. Instead, the focus is on learning and applying various procedures
to solve math problems. That's a bit like explaining soccer by saying it is executing a series of maneuvers
to get the ball into the goal. Both accurately describe various key features, but they miss the \what?"
and the \why?" of the big picture.”
― Keith Devlin, Introduction to Mathematical Thinking
