Mathematical Problems and Puzzles from the Polish Mathematical Olympiads
This book is a translation of the second Polish edition, published in 1960, in which various improvements were made. The contest for secondary school pupils known as the Mathematical Olympiad has been held in Poland every year since 1949/50. The problems set at the contests require only a knowledge of school mathematics (i.e., elementary algebra, geometry and trigonometry) but are on the whole more difficult than the usual school exercises.
