Best Answer

It means that everything in Set A in part of Set B

An example would be:

Set A = The Vowels in the alphabet = (A, E, I , O , U)

Set B = All the letters in the Alphabet = (A B C D E F G H I J K L M N O P Q R S T U V W X Y Z)

As all of the elements (parts) in Set A are also found in Set B along with others, Set A is said to be a Sub Part of Set B

What is mean by Subset in Mathematics?

If all the elements in set A are also elements of set B, then set A is a subset of set B.


What do you call sets within another set?

If all elements of set A are also elements of set B, then set A is a subset of set B.


What the universal set and a subset?

It is the set of all elements we are considering or dealing with in a given problem. We use a capital U or sometimes capital E to mean the universal set. Now take ANY two sets, A and B. If every single element of set A is contained in set B, we say A is a subset of B. The empty set is a subset of every set. Every set in contained in the universal set, so they are all subset of it.


What is a proper 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.


What is a subset in maths?

A set "A" is said to be a subset of of set "B", if every element in set "A" is also an element of set "B". If "A" is a subset of "B" and the sets are not equal, "A" is said to be a proper subset of "B". For example: the set of natural numbers is a subset of itself. The set of square numbers is a subset (and also a proper subset) of the set of natural numbers.


What is a different from subset and proper subset?

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


Example of subset of a line?

let A be the set {1,2,3,4} let B the set {1,3} let C be the set {1,2,4,5} from this, we can say that B is a subset of a because all of the members of B are also member of in another.


What is a subset of a line in geometry?

A set A is a subset of a set B if A is "contained" inside B.


What is an proper subset?

Set "A" is said to be a subset of set "B" if it fulfills the following two conditions:A is a subset of B, andA is not equal to B


What is a subsets?

A is a subset of a set B if every element of A is also an element of B.


An example of why any subset can not be a proper subset?

Assume that set A is a subset of set B. If sets A and B are equal (they contain the same elements), then A is NOT a proper subset of B, otherwise, it is.


What does it means to say that set a is a subset of set b?

It means that all elements in A are included in set B, but not necessarily the other way around.
