If something belongs to set then it means thats it is an element of that set as a whole but if a set is a subset of another set th. The point is that every set is a subset of itself, namely A⊆A - always.

However ∈ does not have this property, for example ∅ has no elements. Describes how sets and subsets are used in statistics and probability. Introduces set notation. Each object in a set is called an element of the set. Two sets are.

Hence we can say that A belongs to B but here a is not a subset of B as any individual element of A won 't be an element of set B. Whether you list them in numerical order or alphabetical order, this is still the set of all one-digit prime numbers. I understand this too.

## Set theory difference between belong/contained and includes/subset Mathematics Stack Exchange

We can list each element (or "member") of a set inside curly brackets like this: Set Notation A ⊆ B, Subset: A has some (or all) elements of B, {3,4,5} ⊆ D. A ⊂ B, Proper Subset: A A − B, Difference: in A but not in B, {1,2,3,4} − {3,4} = {1,2}.

There is not more elaboration on this point in the text. One important difference has already manifested itself above: inclusion is always reflexive, whereas it is not at all clear that belonging is ever reflexive.

I hope after watching this video you will be able to distinguish between a member of a set and subset of a set. Do you have some reference for the history of these two?
