## Calculus (3rd Edition)

$\langle -2, -2, -2\rangle$
We take the cross product: $w\times (u+v) = w\times u + w\times v$ $=-u\times w - v\times w$ Since $u\times w$ and $v\times w$ are given: $=-\langle 0,3,1\rangle-\langle 2,-1,1\rangle$ Distribute the negatives and add: $=\langle -2, -2, -2\rangle$
