Inequalities
Akopọ
Equations tell you exactly where two expressions are equal, but in mathematics and real life you often need to know where one quantity is larger or smaller than another. Inequalities give you a way to describe entire ranges of values, not just single solutions, and they appear throughout the 4PM1 specification whenever a question asks for a set of values rather than a point.
You will learn to solve linear and quadratic inequalities algebraically, represent linear inequalities in two variables on a coordinate grid, and tackle introductory linear programming problems. Every technique builds on algebra you already know, with a few critical sign rules that catch out even confident students.
