Below is a diagram of the dotted cube with edges of length $2$. Suppose vectors $\mathbf{u} = \langle2,0,0\rangle$, $\mathbf{v}=\langle0,2,0\rangle$, and $\mathbf{w} = \langle0,0,2\rangle$. Find the following vectors.

---

1. $\mathbf{u} +\mathbf{v} + 2\mathbf{w} =$

2. $\mathbf{t} =$

3. $\mathbf{t}-2\mathbf{r} =$

4. $\mathbf{u}+\mathbf{v} + \mathbf{w} + \mathbf{r}+\mathbf{s} + \mathbf{t} =$
