Algebra Calculators

Algebra is the language of unknowns — and these calculators speak it fluently. Solve quadratic and cubic equations, crack 2×2 and 3×3 systems of linear equations, explore sequences and series, evaluate polynomials, and work with matrices, vectors, and complex numbers. Each tool shows its method step by step, so you don't just get an answer, you understand how it was found. Whether you're checking homework, preparing for exams, or solving real engineering problems, start with the tool that matches your equation.

  • Complex Number

    Perform calculations with complex numbers in the form a + bi.

  • Cubic Equation Solver

    Find all roots (real and complex) of cubic equations.

  • Linear Inequality Solver

    Solve linear inequalities of the form ax + b c, etc.

  • Logarithm

    Calculate logarithms with different bases. Choose natural log (ln), common log (log base 10), or enter a custom base.

  • Matrix

    Perform matrix operations including addition, multiplication, determinant, and inverse.

  • Polynomial Solver

    Find the roots of polynomials up to degree 4.

  • Quadratic Formula

    Solve any quadratic equation ax2 + bx + c = 0 using the quadratic formula. Get real and complex roots with step-by-step solutions and discri

  • Sequence & Series

    Calculate nth term and sum of arithmetic or geometric sequences.

  • System of Linear Equations Solver

    Solve systems of 2 or 3 linear equations with multiple unknowns.

  • Vector
