Revise: Vector ArithmeticA scalar is an ordinary number.
Specification G25 · Paper 1, Paper 2, Paper 3
A number with magnitude but no direction; it can multiply a vector to change its magnitude and possibly its direction.
To prove that lines are parallel, show explicitly that one non-zero vector is a scalar multiple of the other, then state the geometric conclusion.
For a collinearity proof, identify the common point as well as the scalar-multiple relationship; parallel vectors alone could lie on different lines.
Apply the usual order of operations: perform scalar multiplication before vector addition or subtraction unless brackets change the order.

A scalar is an ordinary number.
A number that multiplies a vector, changing its length and, if negative, reversing its direction.
