Matrix Calculator (2×2) — FAQs

What is a determinant?

For 2×2: ad − bc. Zero means the matrix is singular (no inverse) — its rows are linearly dependent.

Can this do 3×3 matrices?

This tool covers 2×2 — determinant, inverse, trace and multiplication. For 3×3+, dedicated CAS tools handle the algebra.
