The empty set is a set that has no elements in it. Therefore, there is only one empty set. It is written as {}, or as a zero with a diagonal line through it. It might be defined with any rule that can't be fulfilled, such as "the set of prime numbers greater than 7 and smaller than 11", "the intersection of the solutions of (x > 10) and (x < 0)", etc.

Is the union of disjoint sets is always the empty set?
No, only if both sets are empty. The intersection of disjoint sets is always empty.
What are disjoint sets with Example?
Disjoint sets are sets whose intersection is the empty set. That is, they have no elements in common. Examples: {Odd integers} and {Multiples of 6}. {People living in my street} and {Objects made of glass}.
What is the symbol for joint sets?
There is no such symbol for joint sets. Actually, there is a representation for joint sets. That is: The sets are joint if A ∩ B is not empty. The sets are disjoint if A ∩ B is empty.
What can you say empty sets or null sets?
empty set or null set is a set with no element.
What is empty or null in mathematics?
The terms are usually used to describe sets that contain no elements or empty sets.
How come an empty sets become an empty sets?
An empty set becomes an empty set by virtue of its definition which states that it is a set that contains no elements. In other words, it contains nothing, it is empty!

Do sets always have an intersection that is not the empty set?
No, they do not.

Which set is a subset of every set?
The empty set is a subset of all sets. No other sets have this property.
Why empty set is a set?
The concept of closure: If A and B are sets the intersection of sets is a set. Then if the intersection of two sets is a set and that set could be empty but still a set. The same for union, a set A union set Null is a set by closure,and is the set A.
Are two empty sets equivalent?
Yes, both have cardinality 0.
