Rather than jumping straight to answers, this Case File shows students how to think like an investigator. Each topic is broken down carefully, with clear explanations that make sense even if algebra has felt confusing in the past. Students are shown not just the method, but the reasoning behind it — helping them avoid common mistakes and build lasting understanding.
nside this Case File, students will cover:
Linear and quadratic expressions, including expanding and factorising
Solving linear and quadratic equations step-by-step
Algebraic fractions and equations involving fractions
Understanding functions, notation, domain and range
Interpreting and sketching linear and quadratic graphs
Every section includes worked examples that model clear, exam-ready working, followed by practice questions that gradually increase in difficulty. Full solutions are provided, so students can check their thinking and learn from errors without frustration.
This Case File is ideal for GCSE, IGCCE and secondary-school students who need structure, clarity, and confidence — whether they’re catching up, consolidating learning, or preparing for exams.
It’s not about memorising procedures.
It’s about learning how to approach algebra calmly, logically, and correctly.
These are the topics covered within this Case File. Each topic contains worked solutions covering the most common misconceptions.
