Arithmetic is where the answer is right and everything is nice and you can look out of the window and see the blue sky — or the answer is wrong and you have to start over and try again and see how it comes out this time.

If a man’s wit be wandering, let him study the mathematics.

—Roger Bacon (1214–94) English Philosopher, Scientist
