Determinants. A determinant is a single numerical value that can be computed for a square array. The values of determinants play a theoretical role in matrix analysis and can be used for calculations on small matrices. For matrices greater than 3x3 or 4x4, alternative calculation methods are used in place of determinants.

So for 3x3 matrices, the Determinant will measure whether or not the three rows lie in a plane, or if they ‘fill’ all of three space. Eventually we’ll see this is related to questions of when is a matrix invertible.
