∅.In a Venn Diagram, the empty set A can be shown by not writing any elements in it.
The empty set can also be described in different ways, such as by verbal description, roster notation, and set-builder notation.
Verbal Description | All negative integers greater than 0. |
---|---|
Roster Notation | {} or ∅ |
Set-Builder Notation | {x ∣ x is a negative integer greater than 0} |
It is worth noting that since there are no negative integers greater than zero, this description corresponds to the empty set.
