Add [[6,-4,-2,-1],[3,1,-1,1],[1,-1,3,5]]

Problem

[[6,−4,−2,−1],[3,1,−1,1],[1,−1,3,5]]

Solution

1. Identify the task as the summation of all elements within the given 3×4 matrix.

2. Sum the first row elements: 6 + (-4) + (-2) + (-1) = -1$.

3. Sum the second row elements: 3 + 1 + (-1) + 1 = 4$.

4. Sum the third row elements: 1 + (-1) + 3 + 5 = 8$.

5. Add the row sums together to find the total sum: −1+4+8=11

Final Answer

6+(−4)+(−2)+(−1)+3+1+(−1)+1+1+(−1)+3+5=11
