#### Answer

The statement makes sense.

#### Work Step by Step

Two matrices can be added only if they have the same numbers of rows and columns.
If they are of different orders, there would be a minimum of one extra row or column in one of the matrices; there would be no element in the other matrix to be added to the elements of that extra row or column.
Consider the two matrices of order $2\times 2$ $A=\left( \begin{matrix}
a & b \\
c & d \\
\end{matrix} \right)$ and $B=\left( \begin{matrix}
e & f \\
g & h \\
\end{matrix} \right)$.
The addition operation on the matrices is performed as follows:
$\begin{align}
& A+B=\left( \begin{matrix}
a & b \\
c & d \\
\end{matrix} \right)+\left( \begin{matrix}
e & f \\
g & h \\
\end{matrix} \right) \\
& =\left( \begin{matrix}
a+e & b+f \\
c+g & d+h \\
\end{matrix} \right)
\end{align}$
Therefore, the statement makes sense.
