Verify the associative property \((A + B) + C = A + ( B + C)\) of the given matrices.
 
\(A = \begin{bmatrix}
13 & 7\\ 
3 & 8\\
5 & 1
\end{bmatrix}, B =\begin{bmatrix}
5 & 14\\
16 & 5\\
8 & 14
\end{bmatrix}, C =\begin{bmatrix}
5 & 4\\
7 & 5\\
3 & 1
\end{bmatrix}\)
\((A + B)\)\(=\)
\((A + B) + C\)\(=\)
\((B + C)\)\(=\)
\(A + ( B + C)\)\(=\)
  
The associative property of the matrix \((A + B) + C\)  \(A + ( B + C)\)
