Problem

[[1,0,9,0,−7],[0,1,7,0,7],[0,0,0,1,4],[0,0,0,0,−3]]

Solution

1. Identify the task as the summation of the elements within the provided matrix.

2. Sum the elements of the first row: 1 + 0 + 9 + 0 + (-7) = 3$.

3. Sum the elements of the second row: 0 + 1 + 7 + 0 + 7 = 15$.

4. Sum the elements of the third row: 0 + 0 + 0 + 1 + 4 = 5$.

5. Sum the elements of the fourth row: 0 + 0 + 0 + 0 + (-3) = -3$.

6. Calculate the total sum by adding the results from each row: 3 + 15 + 5 + (-3) = 20$.

Final Answer

(∑_^)((a_i,j))=20
