Let vector \( \mathbf{v} = [4, -3, 2] \). Find the result of \( -2 \mathbf{v} \).

Step 1 ：First, write down the vector \( \mathbf{v} \): \( \mathbf{v} = [4, -3, 2] \).

Step 2 ：Then, multiply each component of \( \mathbf{v} \) by the scalar -2: \( -2 \mathbf{v} = -2*[4, -3, 2] \)

Step 3 ：Finally, calculate the result: \( -2 \mathbf{v} = [-8, 6, -4] \)
