A set is a subset of a another set if all its members are contained within the second set. A set that contains all the member of another set is still a subset of that second set.

A set is a proper subset of another subset if all its members are contained within the second set and there exists at least one other member of the second set that is not in the subset.

Example:

For the set {1, 2, 3, 4, 5}:

- the set {1, 2, 3, 4, 5} is a subset set of {1, 2, 3, 4, 5}
- the set {1, 2, 3} is a subset of {1, 2, 3, 4, 5}, but further it is a proper subset of {1, 2, 3, 4, 5}

An empty set is not a proper subset of an empty set.An empty set is not a proper subset of an empty set.An empty set is not a proper subset of an empty set.An empty set is not a proper subset of an empty set.

yes, if the set being described is empty, we can talk about proper and improper subsets. there are no proper subsets of the empty set. the only subset of the empty set is the empty set itself. to be a proper subset, the subset must be strictly contained. so the empty set is an improper subset of itself, but it is a proper subset of every other set.

A set "A" is said to be a subset of "B" if all elements of set "A" are also elements of set "B".Set "A" is said to be a proper subset of set "B" if: * A is a subset of B, and * A is not identical to B In other words, set "B" would have at least one element that is not an element of set "A". Examples: {1, 2} is a subset of {1, 2}. It is not a proper subset. {1, 3} is a subset of {1, 2, 3}. It is also a proper subset.

The set {1, 3} is a proper subset of {1, 2, 3}.The set {a, b, c, d, e} is a proper subset of the set that contains all the letters in the alphabet.All subsets of a given set are proper subsets, except for the set itself. (Every set is a subset of itself, but not a proper subset.) The empty set is a proper subset of any non-empty set.This sounds like a school question. To answer it, first make up any set you like. Then, as examples of proper subsets, make sets that contain some, but not all, of the members of your original set.

There is no such concept as "proper set". Perhaps you mean "proper subset"; a set "A" is a "proper subset" of another set "B" if:It is a subset (every element of set A is also in set B)The sets are not equal, i.e., there are elements of set B that are not elements of set A.

Because every set is a subset of itself. A proper subset cannot, however, be a proper subset of itself.

the difference between a subset and a proper subset

Since ASCII ⊊ unicode, I don't know if there are ASCII codes for subset and proper subset. There are Unicode characters for subset and proper subset though: Subset: ⊂, &sub;, &#8834; Subset (or equal): ⊆, &sube;, &#8838; Proper subset: ⊊, &#8842;,

A subset of a set S can be S itself. A proper subset cannot.

Proper subset definitionA proper subset of a set A is a subset of A that is not equal to A. In other words, if B is a proper subset of A, then all elements of B are in Abut A contains at least one element that is not in B.For example, if A={1,3,5} then B={1,5} is a proper subset of A. The set C={1,3,5} is a subset of A, but it is not a proper subset of A since C=A. The set D={1,4} is not even a subset of A, since 4 is not an element of A.

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.

It isn't. The empty set is a subset - but not a proper subset - of the empty set.

NO- by definition a set is not a proper subset of itself . ( It is a subset, but not a proper one. )
