The course in basic algebra is devoted to fundamental algebraic notions that are demonstrated on basic algebraic structures. Notions include closure systems, operations, algebras (as sets with operations), homomorphisms, congruences, orderings and the divisibility. Lattices, monoids, groups, rings and fields are regarded as the basic structures. The course also pays attention to modular arithmetic and finite fields.

To obtain "Zápočet", the student has to have an amount of 60 points. These can be gained either from two written tests (maximal 50 points per each), or by correctly solving homework problems (here, the point rating varies).

The exam will be oral. It will consists of three questions; one general asking to overview certain topic, for example, symmetric groups or unique factorization domains, one more specific, for example, to formulate and prove the Lagrange theorem for groups, and one testing the understanding, for example, to find a non-trivial normal subgroup of the group A4 . Students will get time to prepare the answers.
