A set is a collection of objects or things. The objects or things in a set are called elements or members of the set.Consider the colour of the Australian flag(shown below). We can write these colours in a set:C = { blue, red, white}

Let set A be the set of the first square numbers. i.e. A={1, 4, 9, 16}The following statements are true:8 ∈ A reads "8 is an element of set A."n(A)=4 reads "the number of elements in A is 4." or "Set A has four elements."5 ∉ A reads "5 is not an element of set A."
