Math & Statistics Tools

Perform scientific calculations: sin, cos, tan, log, ln, square root, power, factorial, pi, e, and more with expression history.

Enter a number to test if it is prime. Generate all primes in a range or the first N primes. Includes factorization for composite numbers.

Enter matrices and perform operations: addition, subtraction, multiplication, scalar multiplication, transpose, and determinant calculation.

Enter numbers and get descriptive statistics: count, sum, mean, median, mode(s), min, max, range, Q1, Q3, IQR, and outliers.

Enter coefficients a, b, c for a quadratic equation and get both real or complex roots with discriminant and vertex.

Compute n! for n up to 170 (JavaScript limit) with BigInt support. Includes double factorial (n!!) and falling factorial modes.

Enter two or more numbers to find their Greatest Common Divisor (GCD) and Least Common Multiple (LCM) with step-by-step Euclidean algorithm.

Enter n and r to compute permutations (ordered) and combinations (unordered). See the factorial formula breakdown for each result.
