The Answer of For $\vec { u } = \langle 1,2,3 \rangle$ , $\vec { v } = \langle - 1,1 , - 1 \rangle$ , and $\vec { w } = \langle 1,2,1 \rangle$ , find $\vec { u } \cdot ( \vec { v } \times \vec { w } )$

For u⃗=⟨1,2,3⟩\vec { u } = \langle 1,2,3 \rangleu=⟨1,2,3⟩ v⃗=⟨−1,1,−1⟩\vec { v } = \langle - 1,1 , - 1 \ranglev=⟨−1,1,−1⟩

For $\vec { u } = \langle 1,2,3 \rangle$ $\vec { v } = \langle - 1,1 , - 1 \rangle$
