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.
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 — 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.

Standard Deviation Calculator
Calculate mean, median, variance, standard deviation, quartiles, and IQR for any dataset, sample or population.
Open Calculator →PC Bottleneck Calculator (CPU vs GPU)
Estimate whether your CPU or GPU is the limiting factor for gaming, streaming, or rendering. Adjusts for resolution and task, then recommends which component to upgrade.
Open Calculator →Factoring Calculator (Polynomial & Number)
Prime factorization, divisors, GCD/LCM, and quadratic factoring with discriminant and roots.
Open Calculator →Percentage Change Calculator
Compute % change, % increase, % decrease, and % difference between two values - with the formula plugged in.
Open Calculator →Square Root Calculator
Compute square roots, cube roots, and nth roots with principal value, simplified radical form, and imaginary handling.
Open Calculator →Triangle Calculator (SSS, SAS, ASA, AAS, SSA)
Solve any triangle from any three elements. Law of Sines, Law of Cosines, and the ambiguous SSA case.
Open Calculator →Significant Figures Calculator
Count significant figures, round to N sig figs, and perform arithmetic preserving correct sig figs for chemistry, physics, and engineering.
Open Calculator →Fraction Calculator (Add, Subtract, Multiply, Divide)
Add, subtract, multiply, and divide fractions and mixed numbers with full simplification. Results as simplified fraction, mixed number, and decimal.
Open Calculator →Derivative Calculator (Symbolic)
Symbolic derivative of any polynomial, trig, exponential, or logarithmic expression. Optional numerical evaluation at a point.
