यदि \( A=\left[\begin{array}{ccc}1 & 2 & -3 \\ 5 & 0 & 2 \\ 1 & -1 & 1\end{array}\right], B=\left[\begin{array}{ccc}3 & -1 & 2 \\ 4 & 2 & 5 \\ 2 & 0 & 3\end{array}\right] \)
तथा \( C=\left[\begin{array}{ccc}4 & 1 & 2 \\ 0 & 3 & 2 \\ 1 & -2 & 3\end{array}\right] \), तो \( (A+B) \) तथा \( (B-C) \) परिकलित कीजिए। साथ ही सत्यापित कीजिए कि
\[
A+(B-C)=(A+B)-C .
