Think of the letter $\Large\mathsf X$ as four vectors starting from the center and pointing outward. Label the four vectors starting from the top left and proceeding clockwise as $\mathbf u$, $\mathbf v$, $\mathbf w$, $\mathbf z$.
Does $\mathbf u \times \mathbf v$ point in or out of the page? (in/out)
Does $\mathbf u \times \mathbf z$ point in or out of the page? (in/out)
Compute $\mathbf u \times \mathbf w$
$\langle$,,$\rangle$
