The Answer of For $\vec { u } = \langle 1,2 , - 1 \rangle \text { and } \vec { v } = \langle 1,1 , - 2 \rangle$ find $\vec { u } + \vec { v }$ and $\vec { u } - \vec { v }$

For u⃗=⟨1,2,−1⟩ and v⃗=⟨1,1,−2⟩\vec { u } = \langle 1,2 , - 1 \rangle \text { and } \vec { v } = \langle 1,1 , - 2 \rangleu=⟨1,2,−1⟩ and v=⟨1,1,−2⟩

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