Step 1

Step 1: Calculate $A + B - C + D - E$: $A + B - C + D - E = \begin{bmatrix} 4 \\ 3 \\ 1 \end{bmatrix} + \begin{bmatrix} 2 \\ -1 \\ -5 \end{bmatrix} - \begin{bmatrix} 16 \\ -8 \\ -10 \end{bmatrix} + \begin{bmatrix} -9 \\ -5 \\ 7 \end{bmatrix} - \begin{bmatrix} 16 \\ Show more…

Consider the following vectors (in column format): $A = \begin{bmatrix} 4 \\ 3 \\ 1 \end{bmatrix}$; $B = \begin{bmatrix} 2 \\ -1 \\ -5 \end{bmatrix}$; $C = \begin{bmatrix} 16 \\ -8 \\ -10 \end{bmatrix}$; $D = \begin{bmatrix} -9 \\ -5 \\ 7 \end{bmatrix}$; $E = \begin{bmatrix} 16 \\ -8 \\ -10 \end{bmatrix}$. Find $A + B - C + D - E$, $|A \times B|$ and $A \cdot (A \times C)$
