Modulus Equations & Inequalities | 25 Worked Examples | Edexcel A-Level Maths

25 progressive Edexcel A-Level (9MA0) modulus equations and inequalities questions with full mark-scheme style worked solutions.

What’s inside:
Easy: solving |ax + b| = c, and sketching the graph of y = |ax + b|.
Medium: solving |f(x)| = |g(x)| and |f(x)| = g(x), and reading off modulus inequalities from a graph.
Hard: harder modulus inequalities, combining two modulus terms, and identifying valid regions.

Every solution shows every step, with M1 (method), A1 (accuracy) and B1 (independent) marks annotated at exactly the point each would be awarded. Typeset in LaTeX for clean mathematical notation.

Ideal for: Year 13 students sitting Edexcel A-Level Mathematics (9MA0) Paper 1 / Paper 2 Pure, plus tutors and teachers building targeted practice. Print-friendly, hand straight to students.
