Lectures (Theoretical lectures). Mathematical logic, propositional and predicate calculus. Set theory and set operations. Relations. Properties of binary relations, equivalence and order relations. Functions and operations. Properties of binary operations. Boolean algebra. Algebraic structures - groups, rings and fields. Polynomials. Complex numbers. Free vectors. Determinants, systems of linear equations, vector space, matrices, linear transformations of vector space, eigenvalues and eigenvectors. Analytical geometry in space. Practice lectures in practice classes: adequate examples and tests from the theoretical lectures are done in order to exercise lectured theory where exercises contribute to understanding of the theory.
