First, Check To Make Sure That You Can Multiply The Two Matrices.

This is an entirely different operation. Ans.1 you can only multiply two matrices if their dimensions are compatible, which indicates the number of columns in the first matrix is identical to the number of rows in the second matrix. Multiplying two matrices is only possible when the matrices have the right dimensions.
