No. A column matrix is an __ordered__ list of numbers.
This means that each position of the column matrix contains a particular number
(or variable.)

Column matrices are awkward in printed text. It is common to print a column matrix like this:

(2.9, -4.6, 0.0)^{T}

The "T" stands for **transpose**,
which means to change rows into columns
(later on a more elaborate definition of "transpose" will be needed.)

Is (1.2, -3.9, 0.0) equal to (1.2, -3.9, 0.0)^{T}
