arithmetic -- improve your arithmetic skills.
arithmetic [-o +-x/] [-r range]
arithmetic prompts you with simple arithmetic exercises, and verifies your answers. arithmetic will reply with Right! if you answered correctly, and with What? if you answered incorrectly. If arithmetic thinks your answer is not a number, it will respond with Please type a number! and repeat the exercise.
After 20 questions, arithmetic will tell you how many exercises you answered correctly, and how much time it took. Interrupting the game triggers the same reports; the game is then terminated.
If you answer an exercise incorrectly, arithmetic will remember the numbers involved, and favour those over others.
arithmetic accepts the following options:
The working of arithmetic is not influenced by any environment variables.
This implementation of arithmetic does not respect the end of file character.
