- Arithmetic: divisibility theory in the ring of integers and of polinomials over a field.
- Congruences. Chinese remainder theorem.
- Rings: subrings, ideals, quotients, isomorphism theorem, ring of polynomials, domains, euclidean rings, PID, UFD.
- Fields: simple field extensions, finite fields.
- Matrices and systems of linear equations: Gauss reduction, determinants.
