Inequalities | OCR GCSE Higher Maths | 40 Worked Examples (J560)

A complete, fully worked pack of 40 inequality questions for OCR GCSE (9-1) Higher Mathematics (J560), ramped from Easy to Challenging. Covers everything OCR examines at Higher tier: solving linear inequalities in one variable, representing solutions on a number line, double inequalities, listing integer solutions, set notation {x : …}, quadratic inequalities solved by factorising and reading off the correct region, and linear inequalities in two variables shown as a shaded, labelled region R on a grid. Every worked solution is broken down one atomic step at a time, with a plain-English note on every line and OCR M/A/B mark-scheme annotations folded in on the real mark-earning lines, including the golden rule that multiplying or dividing by a negative flips the sign, and the dashed-versus-solid boundary-line convention for regions. Ideal for the non-calculator Higher paper J560/05. Written and hand-checked for the OCR specification, which provides no formula sheet.
