Now an n-vector may be displayed either as a row-vector, or a column-vector.

As a row-vector:

\\[

\begin{bmatrix}

4 & 2 & 3

\end{bmatrix}

\\]

As a column-vector:

\\[

\begin{bmatrix}

4 \\\\

2 \\\\

3 \\\\

\end{bmatrix}

\\]

In general, we'll work with column vectors as the default representation.
