What are the set operations and give examples?

2 Set Operations. The union of two sets is a set containing all elements that are in A or in B (possibly both). For example, {1,2}∪{2,3}={1,2,3}. Thus, we can write x∈(A∪B) if and only if (x∈A) or (x∈B).

It is usually denoted by A’ or Ac. A’ = = {x ∈ U : x ∉ A}

What is upside down U in math?

In math, the symbol U represents the union of two sets, while upside-down U represents the intersection of the sets.

What does ∈ mean?

is an element of

The symbol ∈ indicates set membership and means “is an element of” so that the statement x∈A means that x is an element of the set A. In other words, x is one of the objects in the collection of (possibly many) objects in the set A.
