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

Problem

[[1,−2,3,−2],[3,1,−1,−5],[2,3,−5,−5]]

Solution

1. Identify the task as the addition of the elements within the given matrix, which is often interpreted as finding the sum of all entries in the matrix.

2. Sum the first row of the matrix.

1+(−2)+3+(−2)=0

3. Sum the second row of the matrix.

3+1+(−1)+(−5)=−2

4. Sum the third row of the matrix.

2+3+(−5)+(−5)=−5

5. Calculate the total sum by adding the results from each row together.

0+(−2)+(−5)=−7

Final Answer

(∑_^)((a_i,j))=−7
