Discrete mathematics MAA 103 (École polytechnique,
Bachelor, 2017-2019)
Discrete Mathematics MAA 103 (Year 1) had two main objectives: (i)
teach fundamental concepts in discrete mathematics, which are the
building blocks of many different areas of science and of advanced
mathematics (ii) teach how to write proofs. The course started with
elementary logic (e.g. quantifiers, different methods of proof), sets,
and functions. The second part of the course introduced students to
combinatorics and probability (on finite sets). The course consisted of
16 weeks (1h30 lecture and 1h30 exercise session per week).
