Basic Mathematics by Serge Lang - 17.5 Properties of 3x3 Determinants (Basic Mathematics)

Determinants of 2x2 matrices were comparable to a multiplication of sorts of 2-vectors. Determinants of 3x3 matrices are comparable to multiplication of 3 3-vectors. Here, we explore the properties or commutation, distribution, and more. With these simple properties, finding the determinants should be much more interesting and easier.
