-You add corresponding entries when adding matrices.

-You multiply every entry by the number to complete scalar multiplication.

Solve.

1. [-3 + [1 = [-2

0] 2] 2]

2. [12 7] + [3 -4] = [15 3]

3. [8 1 - [3 -2 = [5 3

-1 5] 4 -1 ] -5 6 ]

4. [1 -1 0] - [6 -9 -1]= [-5 8 1]

5. [8 2 -2 + [12 3 10 = [20 5 8

-3 1 14] 0 0 -6 ] -3 1 8 ]
