“Mathematics, you see, is not a spectator sport. To understand mathematics means to be able to do mathematics. And what does it mean [to be] doing mathematics? In the first place, it means to be able to solve mathematical problems.”
— George Pólya, How to Solve It: A New Aspect of Mathematical Method
