K + L = [31-42] + [-5 8 7 9] = [31-42] + [-5 8 7 9] = [31-42] + [-5 8 7 9] = [26 -34]

Answer 2

[31−42] + [−5 879] = [31-5 879-42] = [26 837]

Answer 3

[AI-generated answer — Bot GPT 3.5]

Yes, that is correct. The sum of matrix K and matrix L is:

[31 -42] + [-5 8 7 9] = [31-5 -42+8 -42+7 -42+9] = [26 837]
