We all have learnt about sets, subsets and set theory. All these are interrelated to each other. Let us summarize about sets in this addition.

SUBSETS
Below is a detailed meaning and explanation of Subsets.
If every element of a set B is also a member of a set A, then we say B is a subset of A. The relationship of one set being a subset of another is called inclusion or sometimes containment. The empty set is subsets of every set and every set is a subset of itself. The set C is called a proper subset of D , if C D and C/=D . In this case, we do not use C D . A set A is a proper subset of a set B if A is a subset of B but A is not equal to B.
Let us now see the formula in Math Subsets.
The number of subsets for a finite set A is given by the formula:
Number of subsets = 2 n(A)
where n(A) = number of elements in the finite set A
In mathematics, especially in set theory, a set A is a subset of a set B if A is "contained" inside B. A and B may coincide. The relationship of one set being a subset of another is called inclusion or sometimes containment.
Example : A = { 1,5,3,8,} , B = { 3,5} ,Here B is subset of A. That is B A
That's it for today will be back with more topics in math.
