"Web7 Answers. For ordinary numbers a b means the solution to the equation x b = a. This is the same as b x = a, but since matrix multiplication is not commutative, there are two different possible generalizations of "division" to matrices. If B is invertible, then you can form A B − 1 or B − 1 A, but these are not in general the same matrix. " - Matrix inversion operation

WebTo see why matrix inversion is similar to division, consider a {1*1} matrix -- i.e. a scalar -- with a value of 5. The identity matrix of the same size will also be a scalar, in this case the single value 1. From this it follows that the inverse of the original matrix (scalar) will be the reciprocal of its value. Thus: (1/5)*5 = 1
