what is the difference between "belongs to" and "subset of"?
e.g- if A={1,2,3,4,5,6} and B={1,3,5,7,9} so {1,3,5} belongs to B
will {1,3,5} also be a subset of B?

eg. if we have a set A={1.2} where 1 is an element of A
we can say 1 belongs to A. Also, when we make subsets of set A:
{1},{2},{1,2}
{1} is a subset of a not 1.
in the given eg:-
 {1,3,5} is a subset of B whereas 1,3,5 belong to B..

Hope it helped :)
