Algebra

Number theory

  • Prime factorization calculator

    Write an integer as a product of prime powers, with an exact-integer factorization path.

  • Euler totient (phi) calculator

    Calculate Euler's totient: count positive integers up to the input that are coprime to it.

  • GCD calculator

    Find the greatest common divisor of integers: the largest positive integer dividing them all.

  • LCM calculator

    Find the least common multiple of integers for common denominators and repeating cycles.

Linear algebra

  • Matrix calculator

    Edit native matrices and calculate matrix arithmetic without flattening rows into plain text.

  • Determinant calculator

    Compute the determinant of a square matrix in an editable matrix layout.

  • Inverse matrix calculator

    Find a supported matrix inverse while preserving readable fractional entries.

  • RREF calculator

    Reduce a matrix to reduced row echelon form for linear algebra work.

  • Eigenvalue calculator

    Find eigenvalues of supported square matrices, with exact or approximate output depending on the problem.

  • Cross product calculator

    Calculate the cross product of two three-dimensional vectors and keep the result in native vector notation.

  • Dot product calculator

    Calculate the scalar product of two vectors by multiplying matching coordinates and adding them.

Functions

  • Scientific calculator

    Use fractions, powers, roots, logarithms and trigonometric functions with a visual math keyboard.

  • Special functions calculator

    Explore supported named functions in the same equation editor used for ordinary calculations.

  • Gamma function calculator

    Evaluate supported Gamma-function values, including exact half-integer examples.

  • Lambert W calculator

    Evaluate supported values of the Lambert W function, the inverse of a variable multiplied by its exponential.

Editors

  • LaTeX equation editor

    Write rendered mathematical formulas with fractions, scripts, matrices and a shared math keyboard.

  • Commutative diagram editor

    Build math-labeled commutative diagrams with nodes and configurable arrows.

  • Graph editor

    Create node-and-edge graphs with mathematical labels and free-form positions.
