Maths: Learn & Solve

Learn the math. Solve the puzzle. Maths: Learn & Solve brings interactive lessons and crossing-equation puzzles together. Explore arithmetic, algebra, trigonometry, powers and logarithms, then put the ideas into practice. SEE HOW MATH WORKS Explore number lines, balance scales, variables, the unit circle and doubling trees. Change values and see how the visual examples respond. Each topic includes lessons and quizzes to help you connect the ideas. FOUR TOPICS TO EXPLORE • Arithmetic: number operations, fractions, negative numbers and order of operations. • Algebra: variables, equations, like terms, brackets and two unknowns. Explore coordinates and quadratics as you progress. • Trigonometry: angles, right triangles, sine and cosine, radians, the unit circle and waves. • Powers and logarithms: whole-number powers, roots, negative and fractional exponents, and logarithms. SOLVE CROSSING EQUATIONS Tap a blank cell, choose an answer tile and make the crossing equations work together. Choose Easy, Medium or Hard practice. Check your answers and use the worked explanation to reconsider a mistake. FOLLOW YOUR PROGRESS Track solved puzzles, first-check accuracy, practice streaks and completed chapters. Earn medals and mastery badges as you practice. LEARN AT YOUR OWN PACE Start with a familiar topic or use the lessons for revision. You do not need to finish every topic before exploring another.
