The determinant of a square matrix encodes whether it's invertible (det≠0), the volume scaling of the linear transformation, and orientation change. det=0 → singular matrix.

- 12×2: det [[a,b],[c,d]] = ad − bc
- 23×3: cofactor expansion along first row
- 3det<0 → transformation reverses orientation

2×2 matrix [[a,b],[c,d]]
Resultat
det = ad − bc
For [[3,1],[2,4]]: det = 12−2 = 10
