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

Problem

[[3,1,1],[2,4,2],[−1,−1,1]]

Solution

1. Identify the operation. The task asks to "Add" the given matrix, but since only one matrix is provided, this typically implies summing the individual elements of the matrix.

2. Sum the elements of the first row: 3 + 1 + 1 = 5$.

3. Sum the elements of the second row: 2 + 4 + 2 = 8$.

4. Sum the elements of the third row: −1+(−1)+1=−1

5. Calculate the total sum of all elements: 5 + 8 + (-1) = 12$.

Final Answer

(∑_^)((a_i,j))=12
