Step 1 :Given two matrices A and B as follows:
Step 2 :\[ A = \left(\begin{array}{ccc} -4 & 6 & 3 \\ 0 & 1 & 2 \end{array}\right) \]
Step 3 :\[ B = \left(\begin{array}{ccc} 5 & -1 & 0 \\ 3 & 1 & 0 \end{array}\right) \]
Step 4 :The addition of two matrices is performed element-wise, meaning that each element in the first matrix is added to the corresponding element in the second matrix.
Step 5 :Performing the addition, we get the matrix C as follows:
Step 6 :\[ C = \left(\begin{array}{ccc} 1 & 5 & 3 \\ 3 & 2 & 2 \end{array}\right) \]
Step 7 :Final Answer: The sum of the two matrices A and B is
Step 8 :\[\boxed{\begin{array}{ccc} 1 & 5 & 3 \\ 3 & 2 & 2 \end{array}}\]
