An associative operation is a binary operation where
(a * b) * c = a * (b * c)
i.e neither operation takes priority (however order is still preserved).
Examples of associative operations are:
* multiplication of integers
* intersection of sets.
Examples of non-associative operations are:
* subtraction of integers
#Interesting example from a different area of maths please?# * averaging
* vector cross product
