Linear Algebra Solver
Enter matrix A and, optionally, the right-hand side b. The tool works with exact rational numbers: it computes RREF, det(A), inverse matrices, and Ax=b systems with row-operation steps.
Input
Separate rows with line breaks or semicolons, and entries with spaces or commas. Integers, decimals, and fractions such as 7/12 are supported.
Examples
Result
Choose an action to see the computation.
Row operations
No row operations were needed.
Why this is useful
- Check linear algebra homework without losing exactness to floating-point rounding.
- See the answer and the elementary row operations that produced it.
- Quickly distinguish a unique solution, an inconsistent system, and a family of parametric solutions.
- Prepare clean fractional answers for notes, reports, or manual-solution checks.
Quick reference
RREF reveals pivot variables, rank, and free parameters. Determinants and inverse matrices are computed through the same row operations. All calculations run locally in the browser.
