Solutions to Vector Addition Problems

1. \[\begin{bmatrix} 8 \\ 4 \\ 3 \end{bmatrix}\]

2. We can consider subtraction of real numbers to just be adding \(-1\) times the second operand (e.g., \(2 - 3 = 2 + (-1 \times 3)\)). We’ll define vector subtraction the same way, so the solution to the problem given is:

   \[\begin{bmatrix} -2 \\ 1 \\ 2 \end{bmatrix}\]
