That's not the mathematical meaning of vector.  It's the "physical" or
"engineering" meaning.  The mathematical meaning of vectors has to do with
linear algebra.  While a vectors can still have many "representation" when
different "basis" is used, it is consistent that multiple real numbers are
used to represent a vector.
