Probably not the explanation you're looking for, but... It seems very long and drawn out

anonymous · Answer

This is geometric algebra ( I have been studying it for a few years now).

The inverse of a vector x is the vector which gives 1 when multiplied by x (using the geometric product).

The GP is ab =¨a dot b + a wedge b and has an inverse.

anonymous · Answer

Geometric algebra is a Clifford Algebra where the focus is on the geometric interpretation of the algebra.

Thanks for the help guys. Apparently they were looking for additive inverses. The sum of the vector and its inverse = 0.
