will become pedantic now, but if A is a matrix, the interpretation of the equations above depends on what "1" and "/" actually mean for you. In general, 1/A does not mean anything when you deal with matrices. The symbol "A^{-1}" is normally used to denote the inverse of A. And the inverse is defined only for square matrices. Hence your "conclusion" is actually a fundamental hypothesys to make those equations mean anything at all:)HND
