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 AS Level Maths Equations and Inequalities for AS 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 and Paper 2 format. Build fluency in the core algebra, surds and trigonometry topics early, since they underpin the calculus, statistics and mechanics content that follows.
