var c = a * 2 # (2, 5) * 2 = (4, 10)
var d = b / 3 # (3, 6) / 3 = (1, 2)
var e = d * -2 # (1, 2) * -2 = (-2, -4)

.. code-tab:: csharp

var c = a * 2; // (2, 5) * 2 = (4, 10)
var d = b / 3; // (3, 6) / 3 = (1, 2)
var e = d * -2; // (1, 2) * -2 = (-2, -4)

.. note:: Multiplying a vector by a scalar does not change its direction, only
its magnitude. This is how you **scale** a vector.
.. note:: Multiplying a vector by a positive scalar does not change its direction, only
its magnitude. Multiplying with a negative scalar results in a vector in the
opposite direction. This is how you **scale** a vector.
