Home › Maths & Statistics Calculators
This category brings together every maths and statistics calculator on Calculate.co.nz in one place, covering algebra, geometry, trigonometry, calculus, probability and statistics, so you can find the right tool without hunting across the site. You will find algebra solvers for quadratics, factoring, polynomial roots and systems of equations, geometry and trigonometry tools for area, volume, perimeter, triangles, circles and the SOHCAHTOA and law of sines and cosines methods, and calculus calculators covering derivatives, integrals, limits and Taylor series. On the statistics side there are tools for mean, median, mode and standard deviation, confidence intervals, regression, correlation, chi-square tests and t-tests, ANOVA, sample size, p-values and the main probability distributions such as binomial, Poisson and normal, plus combinatorics calculators for permutations and combinations. Each calculator takes the numbers you enter and returns an instant result with the working shown step by step, rather than just a final answer, so you can check your own method or learn how the formula is applied. Many are aligned with NCEA Levels 1 to 3, making them useful for homework, revision and exam preparation as well as for teachers preparing examples. Every tool listed below is free to use, needs no sign-up and works on any device. Scroll through the full list to find the calculator you need, then follow the related links on each page to move between connected methods and worked examples.
