Exercise 1 Page 791

Subtract the corresponding elements.

-2 & -3 3 & -1 3 & -4

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

Subtract matrices

0-2 & -3-0 2-(-1) & 0-1 1-(-2) & -1-3
0-2 & -3-0 2+1 & 0-1 1+2 & -1-3
-2 & -3 3 & -1 3 & -4
