The null set. Every set is a subset of itself and so the null set is a subset of the null set.

A "subset" means you can make it out of the pieces in the original set. No matter what set you begin with, you always have the option to choose no pieces at all--that creates the null subset.

Yes the null set is a subset of every set.

The empty set is a subset of all sets. No other sets have this property.

The null set. It is a subset of every set.

yes

Let set A = { 1, 2, 3 } Set A has 3 elements. The subsets of A are {null}, {1}, {2}, {3}, {1,2},{1,3},{1,2,3} This is true that the null set {} is a subset. But how many elements are in the null set? 0 elements. this is why the null set is not an element of any set, but a subset of any set. ====================================== Using the above example, the null set is not an element of the set {1,2,3}, true. {1} is a subset of the set {1,2,3} but it's not an element of the set {1,2,3}, either. Look at the distinction: 1 is an element of the set {1,2,3} but {1} (the set containing the number 1) is not an element of {1,2,3}. If we are just talking about sets of numbers, then another set will never be an element of the set. Numbers will be elements of the set. Other sets will not be elements of the set. Once we start talking about more abstract sets, like sets of sets, then a set can be an element of a set. Take for example the set consisting of the two sets {null} and {1,2}. The null set is an element of this set.

The universal subset is the empty set. It is a subset of all sets.

No. The null set cannot have a proper subset. For any other set, the null set will be a proper subset. There will also be other proper subsets.

There is, because {0} has one element, 0. The set {0} therefore can have infinite sets, providing that, all sets are either null or has one element, 0.

Yes all sets have subsets.Even the null set.

yes!

Yes. A null set is always a subset of any set. Also, any set is a subset of the [relevant] universal set.

The definition of subset is ; Set A is a subset of set B if every member of A is a member of B. The null set is a subset of every set because every member of the null set is a member of every set. This is true because there are no members of the null set, so anything you say about them is vacuously true.

There is only one empty set, also known as the null set. It is the set having no members at all. It is a subset of every set, since it has no member that is not a member of any other set.

empty set or null set is a set with no element.

If set A and set B are two sets then A is a subset of B whose all members are also in set B.

Yes.

Equal sets are the sets that are exactly the same, element for element. A proper subset has some, but not all, of the same elements. An improper subset is an equal set.

A set with only one element in it. The only proper subset of such a set is the null set.

It's an axiom.

Yes. One of the subsets is the set itself. The other is the null set.

A - B is null.=> there are no elements in A - B.=> there are no elements such that they are in A but not in B.=> any element in A is in B.=> A is a subset of B.

The only proper subset of a set comprising one element, is the null set.
