Frequently Asked Questions
What is the difference between element and subset?
An element is a single item in a set. A subset is a set whose elements are all in another set.
What is the empty set?
The empty set contains no elements. It is a subset of every set.
What is a universal set?
The universal set contains all elements under consideration in a given context.
