The figure below shows five named points $A$, $B$, $C$, $D$, and $O$ (the letter O, not the number zero) in $\mathbb{R}^n$ for some $n \geq 2$. Write each of the following vector expressions as a single named vector. For instance, enter $\overrightarrow{AB}$ as AB.

• $-\overrightarrow{BC} =$
• $\overrightarrow{AB} + \overrightarrow{BC} =$
• $\overrightarrow{BA} - \overrightarrow{DA} + \overrightarrow{OC} + \overrightarrow{DO} =$
• $\overrightarrow{AB} + \overrightarrow{CD} - \overrightarrow{BD} + \overrightarrow{CA} + \overrightarrow{BA} + \overrightarrow{BC} =$
