What matrix sizes are supported?

The calculator supports 2×2 and 3×3 square matrices. Choose the size from the dropdown before entering values.

Can I multiply matrices of different sizes?

This calculator works with square matrices of the same size. Both matrices must be the same dimensions (either both 2×2 or both 3×3) for operations that use two matrices.

What does a zero determinant mean?

A zero determinant means the matrix is singular and does not have an inverse. It also means the system of equations represented by the matrix has either no solution or infinitely many solutions.
