- 1.Compute [-7, 7, 6; 9, -4, -6] + [-5, 0, 3; -1, 5, -2].
- 2.Compute [-5, -3; -4, -9; 6, 9] - [8, 7; -5, 6; 7, -6].
- 3.Compute -5 × [6, 1, -1; -8, -7, 7; 1, 7, 1].
- 4.Compute [2, 5; 4, 7] + [-6, -3; 5, -4].
- 5.Compute [-5, -1, 7; -9, -2, -3] - [9, -8, 1; -6, -4, 1].
- 6.Compute -3 × [-2, 4; -1, -7; 3, -5].
- 7.Compute [-9, -2; 7, -9; -4, -4] + [-7, 6; 2, 0; 1, -2].
- 8.Compute [-2, -6, -5; 4, -7, -5] - [-7, 7, 6; -3, 8, 7].
