O-Level Two-dimensional vectors

What the O-Level syllabus expects for Two-dimensional vectors, and how to practise it.

What the syllabus expects

handling the different ways a vector is written: the column arrangement (x y), AB carrying an arrow, a set in bold, and the modulus notation |AB| or |a|
depicting a vector by means of a directed line segment
a translation expressed through a vector
vectors that give position
the modulus of a column vector (x y), which equals √(x² + y²)
combining two vectors by addition or subtraction so that a stated vector is written using two others that lie in the same plane
scaling a vector by multiplying it by a scalar
solving geometry problems with the help of vectors
