✓Basic terminology for equations and inequalities, with examples of linear equations and inequalities, with and without absolute value.
✓Basic concepts related to functions (domain, range, graph, surjection, injection, bijection, inverse, composition) and how to work with them.
✓Functions: monotone (increasing, decreasing), bounded, even, odd; extremum: maximum, minimum, both local and global.
✓Geometrical operations on graphs of functions: translations, reflections, shrinking, dilating. Piecewise functions.
✓Absolute value and its role in computing distances, with geometrical illustrations and functional approach.

✓Various types of proofs: direct, indirect, by contradiction, induction proof, with some examples.
✓Building blocks of mathematical theories: axioms, definitions, theorems, propositions, lemmas, corollaries, etc.
✓Decimal expansion of rational and irrational numbers. Density of Q and R\Q in R.
✓Cardinality of sets: finite sets, N, Z, Q, R; countable and uncountable sets.
✓You will also get a solid background for any future studies in Real Analysis and other courses in university mathematics.
