Question

How do you find Z-Y given `X=[(4,1), (-2,6)]` and `Y=[(0,-3)]` and `Z=[(-1,3), (0,-2)]`?

Answer 1

They are not compatible.

Explanation:

Since Z and Y have different dimensions, we cannot find their difference.

`Z` is a `(2 xx 2)` matrix and `Y` is a `(1 xx 2)`, they cannot be added or subtracted. They are not compatible.

We can only multiply `Y xx Z`, because the width of `Y` matches the height of `Z`.
