Answer
The statement makes sense.
Work Step by Step
The statement makes sense because it may be possible that two different matrices can be multiplied but cannot be added.
If there are two matrices A and B of the order $m\times n\text{ and }n\times p$, respectively, then they can be multiplied and their product will be a resultant matrix of the order $m\times p$. But, since their order is not the same, they cannot be added.
Therefore, the statement makes sense.
