What topics does the Math Solver cover?
The mathsolvers.io Math Solver covers the full range of secondary school maths topics — from basic arithmetic and number operations through to algebra, geometry, trigonometry, statistics and probability. Type a question about percentages (percentage change, reverse percentage, VAT), fractions (simplifying, adding, mixed numbers), algebra (linear equations, quadratics, simultaneous equations), geometry (area, perimeter, Pythagoras, circle theorems), ratio and proportion, factors and multiples (HCF, LCM, prime factorisation), statistics (mean, median, mode, range, probability), or trigonometry (SOH-CAH-TOA, sine rule, cosine rule).
How is this different from a calculator?
Most calculators give you an answer. The mathsolvers.io Math Solver gives you the working. Every result shows the full method, step by step — so you can see how the answer is reached, follow the logic, and actually learn the maths rather than just copy a number. It is designed for students who want to understand, teachers who want worked examples, and parents who want to help at home.
