To solve the problem, we need to compute \( A + B \) and \( B - C \), and then verify that \( A + (B - C) = (A + B) - C \). Given matrices: \[ A = \begin{bmatrix} 1 & 2 & -3 \\ 5 & 0 & 2 \\ 1 & -1 & 1 \end{bmatrix}, \quad B = \begin{bmatrix} 3 & -1 & 2 \\ 4 & 2 & 5 \\ 2 & 0 & 3 \end{bmatrix}, \quad C = \begin{bmatrix} 4 & 1 & 2 \\ 0 & 3 & 2 \\ 1 & -2 & 3 \end{bmatrix} \] ### Step 1: Compute \( A + B \) ...
