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.
