![Suppose \( \mathbf{u} = \mathbf{i} - \mathbf{j} \), \( \mathbf{v} = -2\mathbf{i} + 4\mathbf{j} + 3\mathbf{k} \), and \( \mathbf{w} = -5\mathbf{i} + 4\mathbf{j} \).
Compute the following values:
1. \( |\mathbf{u}| + |\mathbf{v}| = \) [input box]
2. \( |-6\mathbf{u}| + 4|\mathbf{v}| = \) [input box]
3. \( |2\mathbf{u} - 6\mathbf{v} + \mathbf{w}| = \) [input box]
4. \( \left| \frac{1}{|\mathbf{w}|} \mathbf{w} \right| = \) [input box]
