Inelential tasks in elementary presentation. Tasks for combinatorics and probability theory, tasks from different areas of mathematics. Yaglom A.M., Yaglom I.M.

In this book, written by famous domestic mathematicians, most of the tasks refers to mathematical disciplines studied only in higher education - to the theory of probabilities, projective geometry, topology, integral calculation, and theory of numbers. At the same time, none of the tasks collected here requires to solve knowledge that go beyond the school course of mathematics (except for brief clarifications given in some places of the book before the conditions of the relevant tasks), both by the wording and according to the methods of solving all these The tasks are quite elementary. The book consists of conditions of tasks, solutions and answers with instructions. The main goal of the book is to introduce the reader to a number of mathematical facts, ideas and methods; The form of the task book was chosen in order to stimulate active, creative work on all this material.

The book is designed for the senior schools and primary school students who are fond of mathematics for university students, for teachers of mathematics and in general for all lovers of this science; It can be used in the work of school and student mathematical circles.
