Math & Statistics Calculators

Algebra, geometry, calculus, statistics, and applied science (Ohm's law, ideal gas, molarity). Built for high-school + college coursework and STEM professionals.

58 calculators in this category

Math calculators on this page cover the everyday algebra basics (slope, percentage, fractions, factorial, exponents) all the way to upper-division statistics (z-score, t-test, chi-square, p-value, confidence intervals, linear regression) and physics (Ohm's law, voltage divider, ideal gas law, exponential growth/decay). Each shows the formula used and intermediate steps where helpful β€” verify before you trust, especially for homework and lab work where partial credit depends on showing your method. JavaScript handles the computation; for arbitrary-precision integer math (factorial, prime factorization), BigInt is used.
