a₁₁ = -11
a₁₂ = -16
a₁₃ = 6
a₁₄ = -10
Step-by-step explanation:
The matrix A will therefore appear as;
[ -11 -16 6 -10 ]
Adding matrices of the same size involves adding the individual elements;
A = [ 0 1 -2 3 ] – [ 11 17 -8 13 ]
Substance the individual element in the two matrices that share the same coordinates;
0 – 11 = -11
1 – 17 = -16
-2 - -8 = 6
3 – 13 = -10
