Research in mathematics is much more than solving puzzles, but most people will agree that solving puzzles is not just fun: it helps focus the mind and increases one's armory of techniques for doing mathematics. ***Mathematical Puzzles***makes this connection explicit by isolating important mathematical methods, then using them to solve puzzles and prove a theorem.

This Revised Edition has been thoroughly edited to correct errors and provide clarifications, and includes some totally different solutions, modified puzzles, and one entirely new puzzle.

Features

• A collection of the world’s best mathematical puzzles


• Each chapter features a technique for solving mathematical puzzles, examples, and finally a genuine theorem of mathematics that features that technique in its proof


• Puzzles that are entertaining, mystifying, paradoxical, and satisfying; they are not just exercises or contest problems.
