[tex] A = \left[\begin{array}{cc}1 & -2 & -3\\ 3 & 7 & 6 \\ 5 & 10 & 7 \end{array}\right] \\
C = \left[\begin{array}{cc}1 & 0 & 0\\ 0 & 1 & 0 \\ 0 & 0 & 1 \end{array}\right] \\
\\
(A + C) = \left[\begin{array}{cc}1 & -2 & -3\\ 3 & 7 & 6 \\ 5 & 10 & 7 \end{array}\right] + \left[\begin{array}{cc}1 & 0 & 0 \\ 0 & 1 & 0 \\ 0 & 0 & 1 \end{array}\right] \\
= \left[\begin{array}{cc}2 & -2 & -3\\ 3 & 8 & 6 \\ 5 & 10 & 8 \end{array}\right] \\

(A + C)^T = \left[\begin{array}{cc}2 & -2 & -3\\ 3 & 8 & 6 \\ 5 & 10 & 8 \end{array}\right]^T \\
