Answer 4

In a sense, yes, to add two matrices together, you add each corresponding element in each matrix. Thus, the element at [1,1] in the first is added to the [1,1]th element in the second to get the [1,1]th element in the sum. If you try to add a 2x2 to a 3x2 matrix, when you try to add the [3,1]the element in the second matrix, you have nothing to which you can add it in the first element, and therefor the operation is an improper one.

Answer 5

So do i put no solution or undefined?

Answer 7

Probably no solution, in this case, since the operation itself is improper. The problem is kind of like asking 'what does the sky taste like?'
