3 x 3 multiplication
Multiply two full 3 x 3 matrices
A common linear-algebra workflow where row-by-column products matter more than elementwise changes.
Result: [14, 14, 20] · [6, 3, 8] · [47, 58, 69]
2 x 2 determinant
Quick determinant check before solving or inverting
Useful when you only need to know whether a small matrix is singular.
Result: det(A) = 10
2 x 2 inverse
Invert a non-singular matrix
A standard classroom example where the determinant stays comfortably away from zero.
Result: [0.6, -0.7] · [-0.2, 0.4]
