is a subset of and is a subset of , is intersection not equal to
by definition:
If and are sets and every element of is also an element of , then:
is a subset of (or is included in) ,(means can have more elements then )
If and are sets and every element of is also an element of ,(means can have more elements then ) then:
is a subset of (or is included in) ,
intersection could be equal to if intersection has no more elements except elements of set
so, if there are any elements in intersection that are not elements of set , then intersection equal to
