Beginning with elementary number theory students move on to a study of symmetries, permutations and their cycle structure. There then follows a more abstract treatment of functions and relations as subsets of the Cartesian product, equiv relations and partitions, which are applied eg to the construction of the rational numbers. This leads naturally in to group theory - including the axioms for a group, subgroups, proof of uniqueness of unit and inverse, examples of groups, corsets, Lagrange's Theorem and its applications. The second half is devoted to an introduction to analysis - covering real numbers: axioms for the field of real numbers: revision of modulus and inequalities, harder inequalties; completeness axiom and simple consequences. Sequences: convergence; theorems on limits; monotonic sequences; Bolzano-Weirstrass Theorem. These ideas culminate in a study of infinite series - including convergence; series of positive terms; geometric series; comparison test; absolute convergence; ratio test

Learning Outcomes
