Example VA Addition of two vectors in $\complex{4}$

If \begin{align*} \vect{u}=\colvector{2\\-3\\4\\2}&&\vect{v}=\colvector{-1\\5\\2\\-7} \end{align*} then \begin{equation*}\vect{u}+\vect{v}= \colvector{2\\-3\\4\\2}+\colvector{-1\\5\\2\\-7}= \colvector{2+(-1)\\-3+5\\4+2\\2+(-7)}= \colvector{1\\2\\6\\-5}\end{equation*}
