Dividing matrices HI Im learning about matrices in school and am curious about how to divide them so i can find out different identity matrices for refecting shapes over linear functions

When you are dealing with regular numbers, you can usually just divide two numbers:
$ 1 / 9 \approx .111... $
But not if the denominator is 0:
$ 1 / 0 = \text{undef} $
In general, if we try to define division among matrices we'll have problems with many matrices being incapable of being used to divide other matrices.
The hint is this:
$ 1 / 9 = 1 * 9^{-1} $
In order to define something "like" division among the matrices, we'll just take the inverse of the divisor and multiply it on the right with the dividend.
$ A / B = A B^{-1} $.
But usually we just talk of multiplying on the (left/right) with the inverse of a matrix. The main reason for this is that most matrices are not invertible.
