Sorry, the notation is bit confusing. The 'A' here is a matrix.

I know it is a matrix, the notation is not confusing at all. I am saying that the concept of a matrix as a set of numbers arranged in a rectangles and the concept of operations on a matrix are very different things, the confusion will not come from notation.

You must be correct, because this interaction is completely devoid of any confusion between the two people attempting to communicate clearly.
