Imaginary Matrix Division

[Tonig00]

Interesting, matrix multiplication is not commutative.
If a = [[1 1][1 1]] and b = [[1 1][1 i]]
When ask Prime a/b gives a warning: inv(b)*a

This gives [[1 1][0 0]]

If you do a*inv(b) gives [[1 0][1 0]]

For me exponents should be operate first so prime in this misleading expresión is correct. But I am not sure, could be the opposite.
