The full Cambridge IGCSE Mathematics course, Core and Extended: number, algebra and graphs, coordinate geometry, geometry, mensuration, trigonometry, transformations and vectors, probability and statistics, explained in plain language with worked examples.
Lesson 1 is free to try. The other 121 lessons in Mathematics and its exam practice are for schools on RudimentaryLabs.
Primes, sets, fractions, decimals, powers, roots and standard form, the building blocks for everything else.
Rounding and bounds, ratio, rates, percentages, time, money, growth and decay, and surds.
Use letters for numbers, expand and factorise, handle algebraic fractions and indices, and solve equations of every kind.
Solve inequalities, find rules for sequences, describe proportion and read travel and speed graphs.
Draw and sketch curves, solve equations with graphs, find gradients by differentiation and work with functions.
Straight lines on a grid, their gradients and equations, and how parallel and perpendicular lines are linked.
The language of shapes, constructions, bearings, similarity, symmetry, angle facts and circle theorems.
Measure perimeters, areas, surface areas and volumes of flat shapes and solids, including circles and spheres.
Use the sides and angles of triangles to measure things you cannot reach, in two and three dimensions.
Move, flip, turn and resize shapes, then use vectors to describe movement and prove geometric facts.
Put a number on chance, from single events to combined and conditional probabilities.
Collect, display and summarise data with averages, spread, charts, cumulative frequency and histograms.
