In 1,
Shouldnt it be that the # of rows in A are not equal to the # of columns in B?

[@AnnakayeWalker]

So I just searched. If the # of columns in the first matrix is not equal to the # of rows in the second matrix, then it's NOT possible. So if the # of columns in the first matrix is equal to the # of rows in the second matrix, then it is possible.
