What will I learn?
This course provides a strong foundation in primes, unique factorisation, divisibility, GCD, and the Euclidean algorithm. It then advances to order, well-ordering, and induction using clear examples. You will also cover infinity, bijections, and cardinality, while honing proof techniques and writing skills for precise, organised arguments, computations, and projects.
