Practice Test 6

Vectors $\mathbf{u}=\langle 2,3\rangle$ and $\mathbf{v}=\langle -2,-3\rangle$ are additive inverses. What is $\mathbf{u}+\mathbf{v}$?

Vectors $\mathbf{u}=\langle 1,-2\rangle$, $\mathbf{v}=\langle 4,3\rangle$, and $\mathbf{w}=\langle -2,1\rangle$ are given. Using component-wise addition, what is $\mathbf{u}+\mathbf{v}+\mathbf{w}$?
