More on the Conditional
For each of the four statements below, answer the following questions: Does the statement make sense? If yes, is it true for all possible choices of $\vec{a}$ and $\vec{b}$ ? If no, why not? (a) $\vec{a}+\vec{b}=\vec{b}+\vec{a}$ (b) $\vec{a}+\|\vec{b}\|=\|\vec{a}+\vec{b}\|$ (c) $\|\vec{b}+\vec{a}\|=\|\vec{a}+\vec{b}\|$ (d) $\|\vec{a}+\vec{b}\|=\|\vec{a}\|+\|\vec{b}\|$

Rewrite each pair of conditionals as a biconditional. If $B$ is between $A$ and $C,$ then $A B+B C=A C$ . If $A B+B C=A C$ , then $B$ is between $A$ and $C$ .
