Equation System Solver

Solve up to 12 linear equations in exact fractions, see each Gauss–Jordan row operation, and learn whether there is one, none or infinitely many solutions.

Matrix Calculator

Add, subtract, multiply, transpose, and find the determinant or inverse of a 2x2 or 3x3 matrix. No data ever leaves your device.

Quadratic Solver

Solve ax² + bx + c = 0 for exact radical roots, the discriminant, the vertex and a sketch of the parabola, with every line of working shown.

Why These Tools

Algebra homework rarely fails on the idea. It fails on arithmetic, three rows into an elimination, when a sign flips and every later line inherits the mistake. System of Equations Solver with Steps handles up to 12 linear equations using exact fractions, lists each row operation with the matrix it produces, and says plainly when a system has no solution or infinitely many.

Two older tools live here as well. 2×2 / 3×3 Matrix Calculator finds the determinant and inverse that tell you, before any elimination, whether a square system has a single answer. Quadratic Equation Solver covers the first nonlinear case, with exact radical roots and the working shown. Calculus, vectors, truth tables and Karnaugh maps are planned for this page next.
