Chapter Overview
This chapter introduces the idea of ordered pairs, Cartesian products, relations, and functions — essential tools used to describe and analyze patterns, relationships, and rules in mathematics and science. It builds the groundwork for calculus, coordinate geometry, and computer science applications.
