Analytical Intuition.
The Determinant is the Volume Expander. It tells us how much a transformation stretches or squashes space. Imagine a unit square (area 1). After transformation, its area is the determinant. If zero, space was squashed into a line (singular).
CAUTION
Institutional Warning.
Most only know the cross-multiply formula. The intuition is change of volume.

What is a negative determinant?
It means orientation was flipped?like a transformation in a mirror.
