There are two classes of people posting in this thread. One class confuses arithmetic (and even calculus) with mathematics. These are computational schemes which come from mathematics.
Mathematics is about proofs and is definitely a creative process. There may indeed be "real answers," but in the real mathematical world, nobody knows what they are.
