I am confused as well. This is for physics
Here is the full question
Given the following system of vectors
U=2i+3j+2k
V=-2i+4j-k
W=3i+3k
Find determinant by hand (done)
FInd value of u x v
explain the orientation of this vector in terms of U and V.

you misread the question it says find U*V , so find the cross product of vector U and V not U V and W lol

but for your defense @AmTran_Bus , I think the teacher should have written it out better to empathize with the vector product, like:
\[\Large \vec{a} \times \vec{b}=\vec{n} \]

is the bottom -2, 4, and -1? Ok, um...the letters on top...we have never done this before...the cross product.
