Compute the product $AB$ of the two matrices below using both the definition of the matrix-vector product (Definition MVP) and the definition of matrix multiplication (Definition MM). \begin{align*} A &= \begin{bmatrix} 1 & 3 & 2 \\ -1 & 2 & 1 \\ 0 & 1 & 0 \end{bmatrix} & B &= \begin{bmatrix} 4 & 1 & 2\\ 1 & 0 & 1\\3 & 1 & 5 \end{bmatrix} \end{align*}
