1. Perform the following matrix computation. \begin{equation*} (6) \begin{bmatrix} 2 & -2 & 8 & 1 \\ 4 & 5 & -1 & 3\\ 7 & -3 & 0 & 2 \end{bmatrix} + (-2) \begin{bmatrix} 2 & 7 & 1 & 2\\ 3 & -1 & 0 & 5\\ 1 & 7 & 3 & 3 \end{bmatrix} \end{equation*}
  2. Theorem VSPM reminds you of what previous theorem? How strong is the similarity?
  3. Compute the transpose of the matrix below. \begin{equation*} \begin{bmatrix} 6 & 8 & 4 \\ -2 & 1 & 0 \\ 9 & -5 & 6 \end{bmatrix} \end{equation*}
