8. Check the associative property on 3 × 2 matrix

Verify the associative property $(A + B) + C = A + ( B + C)$ of the given matrices.

 

$A = \begin{bmatrix} 13 & 7\\  3 & 8\\ 5 & 1 \end{bmatrix}, B =\begin{bmatrix} 5 & 14\\ 16 & 5\\ 8 & 14 \end{bmatrix}, C =\begin{bmatrix} 5 & 4\\ 7 & 5\\ 3 & 1 \end{bmatrix}$

  

The associative property of the matrix $(A + B) + C$ ≠= $A + ( B + C)$
