Domain 14 · Mathematics Codex
Recreational, Educational & Pedagogical Mathematics
Mathematics as play — puzzles, paradoxes, games, and the joy of number.
Scope
Mathematical puzzles, recreational problems, mathematical games, number curiosities, magic squares, mathematical art, olympiad mathematics, the history of mathematical education.
Recreational mathematics has often been the entry point for serious mathematical ideas. The Four Colour Theorem began as a puzzle. Euler's solution of the Königsberg bridge problem founded graph theory. The study of what a game-winning strategy is formalized into combinatorial game theory. This domain also includes the International Mathematical Olympiad and the educational tradition of mathematics teaching globally.
