Algebra
Calcolatori di matematica e statistica con formule passo-passo ed esempi svolti per studenti e professionisti.
Quadratic Equation Calculator
Solve ax^2 + bx + c = 0 with the quadratic formula. Shows real or complex roots and the discriminant, with a worked step-by-step example.
Log Calculator
Calculate logarithms in any base with the change-of-base formula, plus the natural log (ln), common log (log10) and binary log (log2) shown together.
Exponent Calculator
Raise any base to any power, including negative and fractional exponents, with the result in plain and scientific notation and the exponent rules explained.
Prime Number Calculator
Check whether a number is prime, get its full prime factorization, and find the next prime — with trial division explained and worked examples.
Matrix Calculator
Calculate the determinant, trace and (for 2x2) inverse of a 2x2 or 3x3 matrix from row-major entries, with cofactor expansion shown step by step.
