yeah!
There is a device that can add, subtract, multiply, divide, do any mathematical problem, write in any language, find out any universal problem, tell you any secret, and solve all human questions. It was invented quite a long time ago, is small enough to fit in your pocket, has a deleting device on it as standard equipment and only costs a few cents. How can a store sell such a magnificent device for a few cents without losing money? What is this great product and why hasn't the world used it for its maximum power?
