 definition of the determinant:
 that is, we're going to define $\det T$
 for $T \colon V \to V$ without making reference to the encoding for $T$.

+This will make it obvious that the determinant of a matrix
 does not depend on the choice of basis,
 and that several properties are vacuously true
 (e.g.\ that the determinant is multiplicative).
