## Complement

### In mathematics, the complement of a set refers to the elements that are not members of the set

In mathematics, the complement of a set refers to the elements that are not members of the set. Let’s say we have a universal set U and a set A. The complement of A is denoted by A’ or Aᶜ.

To find the complement of A, we need to identify all the elements that are in U but not in A. This means we are essentially subtracting the elements in A from the universal set U.

Mathematically, we can express the complement of A as:

A’ = U – A

For example, let’s consider a universal set U = {1, 2, 3, 4, 5} and a set A = {2, 4}. The complement of A would be the elements in U that are not in A.

A’ = U – A = {1, 3, 5}

So, the complement of A is {1, 3, 5}.

It is important to note that the complement of a set depends on the universal set chosen. Different universal sets can yield different complements for the same set.
