#### Work Step by Step

In order to add matrices, we add each number and its corresponding number. Thus, we add the two numbers in the upper left corner of the first two matrices and put the sum in the upper left corner of the new matrix. We do the same thing for the numbers in the upper right corner, lower left corner, and lower right corner. Thus, we obtain the answer:
1 0
1 0
