Problem

[[7,9],[4,5]]+[[9,1],[7,9]]

Solution

1. Identify the operation requested. Although the task says "Multiply", the expression provided uses the addition symbol + Following the mathematical expression, we perform matrix addition.

2. Add the corresponding elements in the first row and first column: 7 + 9 = 16$.

3. Add the corresponding elements in the first row and second column: 9 + 1 = 10$.

4. Add the corresponding elements in the second row and first column: 4 + 7 = 11$.

5. Add the corresponding elements in the second row and second column: 5 + 9 = 14$.

6. Combine these results into a new 2×2 matrix.

Final Answer

[[7,9],[4,5]]+[[9,1],[7,9]]=[[16,10],[11,14]]
