# Discrete Mathematics and Graphs

 Credits 5 Semesters Winter Completion Assessment + Examination Language of teaching English Extent of teaching 3P+1S
Annotation
The aim of the course is to introduce students to fundamentals of Discrete Mathematics with focus on electrical engineering. The content of the course covers fundamentals of propositional and predicate logic, infinite sets with focus on the notion of cardinality of sets, binary relations with focus on equivalences and partial orderings; integers, relation modulo; algebraic structures including Boolean algebras. Further, the course covers basics of the Theory of Graphs.
Study targets
The goal of the course is to introduce students with the basic notions from discrete mathematics, namely logic, basics of set theory, binary relationsand binary operations; basics from graph theory and combinatorics.
