## How do we name a set?

Therefore, any set is actually a named set of the form (X, ∈, “X” ) where X is a set (without a name ), “X” is the name of this set and connects elements from X to the name “X”. The next is basic binary relation ⊆ between two sets called the subset relation, or set inclusion.

## What is an upside down U in math?

In maths, the upside – down U means intersection of sets. The ∩ symbol represents the intersection of two sets. This means the elements that are in common to both sets.

## What is cardinality example?

If A has only a finite number of elements, its cardinality is simply the number of elements in A. For example, if A={2,4,6,8,10}, then |A|=5.
