Introduction to enumerative combinatorics

The manual contains classic enumeration tasks for choosing and organizing the elements of the final set and tasks for the division of final sets and multisets. Basic concepts, facts and methods of enumerable combinatorics are given in the amount allowing a university graduate on a highly significant and methodological level to develop and conduct elective and elective courses on combinatorics in high school. The stated material is also a foundation for studying the serious educational and monographic literature on combinatorics and its applications.
The manual is intended for students of higher educational institutions studying in the direction of 050100 Pedagogical education. It can be used in teaching the Combinatorics section in courses of discrete mathematics, as well as in the development and setting of special courses on the selection of students set by the university. In a profile school, individual sections of the benefits can serve as the basis for elective courses on combinatorics for students of grades 10-11
