**Exercise 10.4.4**

Let \( T : \mathbb{R}^2 \to \mathbb{R}^2 \) be a linear transformation defined by

\[
T \left( \begin{bmatrix} a \\ b \end{bmatrix} \right) = \begin{bmatrix} a + b \\ a - b \end{bmatrix}.
\]

Consider the two bases

\[
B_1 = \left\{ \begin{bmatrix} 1 \\ 0 \end{bmatrix}, \begin{bmatrix} -1 \\ 1 \end{bmatrix} \right\}
\]

and

\[
B_2 = \left\{ \begin{bmatrix} 1 \\ 1 \end{bmatrix}, \begin{bmatrix} 1 \\ -1 \end{bmatrix} \right\}.
\]

Find the matrix \( M_{B_2, B_1} \) of \( T \) with respect to the bases \( B_1 \) and \( B_2 \).
