Exercise 1 Page 729

Add corresponding elements.

- 3 & 9 0 & 4

Practice makes perfect
For the addition of matrices to be possible, they need to have the same dimensions. In the given exercise, both are 2* 2 matrices. This means they both have two rows and two columns. To add these matrices, we add the corresponding elements. Let's do it!
0 & 7 - 4 & 5 + - 3 & 2 4 & - 1

Add matrices

0+(- 3) & 7+2 - 4+4 & 5+(- 1)
0- 3 & 7+2 - 4+4 & 5- 1
- 3 & 9 0 & 4
