So, the problem in the image involves matrix addition. You are given two matrices, $A$ and $B$, and need to find $A + B$.

Matrix $A$ is: $A = \begin{bmatrix} 2 & 3 \\ 1 & 1 \end{bmatrix}$

Matrix $B$ is: $B = \begin{bmatrix} 5 & 6 \\ 2 & 3 \end{bmatrix}$

To add these two matrices, you simply add the corresponding elements:

$A + B = \begin{bmatrix} 2 + 5 & 3 + 6 \\ 1 + 2 & 1 + 3 \end{bmatrix}$

This simplifies to: $A + B = \begin{bmatrix} 7 & 9 \\ 3 & 4 \end{bmatrix}$

So the result of $A + B$ is: $\begin{bmatrix} 7 & 9 \\ 3 & 4 \end{bmatrix}$

Let me know if you'd like a more detailed explanation, or if you have any further questions!
