Course objectives 
To acquaint students with fundamental methods of general and linear algebra, with basic algebraic structures – groups, rings and fields; to create a base for studying basic concepts and methods of modern mathematics; to form mathematical thinking among students; to acquaint with methods of mathematical proofs; to study algorithms for solving specific mathematical problems. To instill in students the ability to independently study educational and scientific literature in the field of mathematics. As a result of studying the course, a student should be able to: – perform operations with complex numbers in algebraic and trigonometric form, to extract roots of complex numbers, use de Moivre formula; – calculate determinants; – perform operations on matrices; – solve systems of linear equations.
