Abstract

This chapter starts with the counting or natural numbers, formalising them using structured types, thus allowing the definition of the standard numeric operators such as addition and multiplication. Using the natural numbers, the notions of mathematical and strong induction are formalised and illustrated through examples. Other classes of numbers, such as the integers, rational numbers and real numbers are also discussed. The notion of cardinality is presented, showing how one can reason about the size of finite, but also infinite sets.
