Free browser-based algebra calculators for equations, inequalities, quadratics, polynomials, matrices, ratios, coordinate forms, exponents, and logarithms.

Primary algebra verification workflows

Round-trip equations, matrices and polynomials instead of trusting one form

These eight GSC-visible workflows add independent equivalence and degeneracy evidence on top of existing solving, graphing, substitution and residual checks.

Matrix InverseA↔A⁻¹ identity round trips MidpointEndpoint reflection round trip Linear EquationScale invariance + degeneracy classes DeterminantTranspose/row-operation invariants Quadratic VertexStandard ↔ vertex coefficient round trip Slope InterceptPoints ↔ line-form equivalence Polynomial DivisionQuotient/remainder reconstruction Standard FormSlope-intercept ↔ standard round trip

Boundary: these are bounded numeric and structural checks. They do not parse arbitrary symbolic algebra, prove identities over every domain, or remove restrictions introduced by division, roots or logarithms.

Recognize → transform → solve → verify

Choose the algebraic form first, follow the supported transformation, then verify the result with an equivalent form, root, factor, matrix, or substitution check.

Equations & inequalities

Solve one-variable equations, systems, and inequalities, then compare equivalent line forms.

Linear Equation CalculatorEnter the supported coefficients, review the isolated variable, and use the connected tools when the relationship changes from equality to inequality or multiple equations.Linear Inequality CalculatorEnter ax + b <, ≤, >, or ≥ c to isolate x and show the sign-reversal rule when dividing by a negative coefficient.System of Equations SolverEnter the system in the supported format, verify the equations, and use the matrix or line-form tools to inspect the same relationship from another representation.Slope Intercept Form CalculatorEnter two points to calculate slope, y-intercept, and the equation of the line.Point Slope Form CalculatorEnter a point and slope to generate point-slope, slope-intercept, and standard-form references.Standard Form Equation CalculatorEnter slope and y-intercept to view equivalent slope-intercept and standard-form equations.

Quadratics

Move between roots, discriminant, factors, vertex form, and completing the square.

Quadratic Formula CalculatorEnter a, b, and c, keep the discriminant visible, and use the connected workflow to compare equivalent quadratic methods instead of treating one formula as a black box.Quadratic Factoring CalculatorEnter a, b, and c for ax² + bx + c to see roots, discriminant, factor form when real, and a concise check.Completing the Square CalculatorEnter ax² + bx + c to calculate h and k, show a(x − h)² + k, and connect the transformation to the vertex.Quadratic Vertex CalculatorEnter a, b, and c for ax² + bx + c to calculate its vertex and key parabola properties.Discriminant CalculatorEnter quadratic coefficients to find the discriminant and root classification.

Polynomials & expressions

Evaluate and divide polynomials, use synthetic division for x − r, and work with powers, logs, scientific notation, and complex values.

Polynomial EvaluatorEnter coefficients from highest power to constant and an x value to calculate P(x).Polynomial Long Division CalculatorEnter polynomial coefficients carefully and use the dedicated synthetic-division tool for a faster structured row when the divisor is linear and monic.Synthetic Division CalculatorEnter polynomial coefficients and r to calculate the quotient, remainder, and synthetic row for division by x − r.Exponent CalculatorEnter a base and exponent to calculate x raised to the power of y.Log CalculatorEnter a positive number and logarithm base to calculate log base b of x.Scientific Notation CalculatorNormalize decimal values to scientific notation, expand notation back to decimal, and multiply or divide two scientific-notation values.Complex Number CalculatorEnter real and imaginary parts for two complex numbers and calculate the result, magnitude, and angle.

Matrices, ratios & coordinate relationships

Inspect matrices and determinants, solve proportions and variation, and connect slope, midpoint, distance, and rate of change.

Matrix CalculatorWork with 2×2 or 3×3 matrices A and B directly in your browser.Matrix Determinant CalculatorPaste a square matrix to calculate its determinant locally using pivoted elimination.Matrix Inverse CalculatorPaste a square matrix to compute its inverse using Gauss-Jordan elimination in your browser.Proportion CalculatorEnter three known terms and one unknown, then use ratio tools for scaling, comparison, or part-to-part interpretation.Direct Variation CalculatorEnter x and the constant of variation k to calculate y and view the direct-variation equation.Inverse Variation CalculatorEnter a nonzero x and the constant of variation k to calculate y and verify xy = k.Slope CalculatorEnter two points to calculate rise over run and the line slope.Distance Formula CalculatorEnter two points to calculate their straight-line distance.Midpoint CalculatorEnter two points to find the midpoint of the line segment.Average Rate of Change CalculatorEnter two points to calculate Δy/Δx, which is the secant slope between them.
