2000 problems from elementary mathematics

This collection of 2000 problems contains the problems of so-called elementary mathematics - independent of the tool system of mathematical analysis. Several of its chapters provide a rich repertoire of problems that other example libraries omit, e.g. functional equations, geometric constructions, combinatorial geometry. And its solutions are concise and striking. It is an indispensable accessory for the toolbox of mathematics teachers. Its history is a success story: it was originally published with 1500 problems, then the favorable reception gave the opportunity to expand, and thus the 2000-problem version was born, which in its renewed, friendlier form, we hope will continue to be a fresh splash of color in mathematics teaching.
