Find the inverse of a square matrix using Gauss-Jordan elimination, with every row operation shown. Exact fractions, no rounding. Dimensions up to 6×6.
Enter the entries of a square matrix — whole numbers, decimals, and fractions like 1/2 are all accepted.
Pick a size from 1×1 to 6×6. Only square matrices have an inverse, so rows and columns always match.
Type a value into each cell. The result updates as you type, and every value is kept as an exact fraction rather than a rounded decimal.
The determinant and inverse appear first, followed by every Gauss-Jordan row operation applied to the augmented matrix. If the determinant is zero, the matrix is singular and has no inverse.
