What will I learn?

This course builds a strong foundation in primes, unique factorisation, divisibility, GCD, and the Euclidean algorithm. It then advances to order, well-ordering, and induction with practical examples. You'll also cover infinity, bijections, and cardinality, while honing proof-writing skills for clear, precise arguments and a solid final project.
