The intersection of two sets S and T is the set of all elements that belong to both S and T.
You need two sets to have an intersection. If you have two sets, call them R and S, then their intersection is the set T that contains all elements of R that also belong to S OR all elements of S and also belong to R...it's the same thing.
The answer depends on what "200" refers to. A null set has no elements, but then it is strange to call it 200!
The objects within a number set can be caled as "Elements" or "members".
Elements, possibly.
The intersection of sets A and B.
The union of sets X and Y is the set consisting of all elements that belong to X, or belong to Y or to both.The union of sets X and Y is the set consisting of all elements that belong to X, or belong to Y or to both.The union of sets X and Y is the set consisting of all elements that belong to X, or belong to Y or to both.The union of sets X and Y is the set consisting of all elements that belong to X, or belong to Y or to both.
Elements belong to subsets: subsets contain elements (from the parent set).

null
A subset, A, of a given a set S, consists of none or more elements that belong to S.
Because all its elements belong to itself.

Sets are just collections of things. A set is defined by the things that belong to it- that is if you have two sets A and B and everything that belongs to A belongs to B and everything that belongs to B belongs to A then A and B are actually the same set. An important example is the empty set - which by definition contains nothing. There is only one empty set. The things that belong to a set are calle its elements There are different ways of defining sets. You can define them by listing their elements, or you can define them by giving one or more properties that uniquely define the elements that belong to the set.

The additive identity for a set is a number (denoted by 0) such that a + 0 = 0 + a = a for all elements a which belong to the set.
