## What is a Set?

A

**set**is an*unordered collection of objects*, usually called*elements*or*members*of the set. We can represent a set by*listing*its elements, or by defining the*property*of all the elements in the set (set-builder notation) Example:*A*={60, 62, 64, 66, 68, 70} and*A*={*x*| 60 ≤*x*< 71,*x*is an even integer} are two representations of the same set. We can also represent sets visually, using Venn diagrams: explore this representation in the app below.
