The basic language

An equation says two expressions are equal, so you usually look for exact value or values that make both sides match. An inequality compares size using $<$ , $>$ , $≤\le$ , or $≥\ge$ , so the answer is often a range of values.

Equations and Inequalities

Step-by-step lessons covering Edexcel A Level Maths Equations and Inequalities for A Level Maths. Each lesson breaks down 3.1 Linear Simultaneous Equations, 3.2 Quadratic Simultaneous Equations, 3.3 Simultaneous Equations on Graphs, 3.4 Linear Inequalities, 3.5 Quadratic Inequalities, and 3.6 Inequalities on Graphs, then works through exam-style questions in Paper 1, Paper 2 and Paper 3 format. Build fluency with the core pure algebra and calculus toolkit early, since almost every mechanics and statistics topic on the course depends on it.
