Groups - Introductory Abstract Algebra (Undergraduate Advanced)

This course introduces groups—one of the fundamental structures in abstract algebra. We cover the group axioms, explore classic examples like integers under addition and symmetry groups, and show how groups model structure and transformations in math. Clear, focused, and designed for learners new to abstract algebra.

MTH 203: Sets, Logic and Algebra I
Abstract algebra is the structural foundation of modern advanced mathematics. This track delivers the complete NUC CCMAS MTH 203 curriculum, rigorously transitioning you from computational arithmetic to abstract mathematical reasoning. It provides the necessary prerequisite framework for understanding complex mathematical systems and their applications. This programme is targeted at undergraduate students in mathematics, computer science, and physics requiring a firm grounding in fundamental algebraic structures. It also serves professionals in fields like cryptography or theoretical computer science who need a rigorous theoretical refresher. You will master the precise definitions, properties, and relations of core algebraic structures, including groups, subgroups, rings, and fields. You will gain competence in constructing formal proofs using set theory and logic, and understand how homomorphisms preserve mathematical structure. Completion establishes the critical theoretical base demanded for advanced studies in algebra, coding theory, and algorithm design.
