If the matrix \( A=\left[\begin{array}{cc}3 & -2 \\ -7 & -8\end{array}\right] \), then additive inverse of
\( \mathrm{P} \)
\( A \) is equal to
(1) \( \left[\begin{array}{cc}-3 & 2 \\ 7 & 8\end{array}\right] \)
(2) \( \left[\begin{array}{cc}-3 & -2 \\ 7 & 8\end{array}\right] \)
(3) \( \left[\begin{array}{cc}3 & -2 \\ -7 & +8\end{array}\right] \)
(4) \( \left[\begin{array}{ll}3 & 2 \\ 7 & 8\end{array}\right] \)
