Mathematical puzzles make up an integral part of recreational mathematics. They have specific rules as do multiplayer games, but they do not usually involve competition between two or more players. Instead, to solve such a puzzle, the solver must find a solution that satisfies the given conditions. Mathematical puzzles require mathematics to solve them. Logic puzzles are a common type of mathematical puzzle.
Conway's Game of Life and fractals, as two examples, may also be considered mathematical puzzles even though the solver interacts with them only at the beginning by providing a set of initial conditions. After these conditions are set, the rules of the puzzle determine all subsequent changes and moves.

Answers:They are called CalcuWords in one puzzle magazine I get.
Answers:Navy (above) is absolutely correct. Although, in his own words, fuzzy on the history, Fermat stated centuries ago that this is impossible. Of course we are all familiar with Pathagoras: a^2 + b^2 = c^2 But Fermat conjectured about powers higher than two. What about 3? What about 4? Etc. And so his famous "last theorem" was: a^n + b^n = c^n And he said that no known interger greater than 2 would be possible. So a^3 + b^3 = c^3 is impossible, according to Fermat. The really remarkable thing is that Fermat's theorem was not proved until 1996!! The famous British-American mathematician Andrew Wiles in 1993 produced a proof. Soon after, however, some fundamental errors arose in his monumental work, and he was forced into working on correcting these errors before submitting a final version of his proof in October of 1996. It is literally hundreds of pages long but shows the impossibility of n>2. :)
