A **set** is a well-defined collection of distinct objects, considered as an object in its own right. The objects in a set are called its elements or members. Sets can contain anything: numbers, letters, symbols, or even other sets. Sets are usually denoted by curly braces `{}`.
### Examples of Sets:
1. **Set of Natural Numbers Less Than 5**:
\[
A = \{1, 2, 3, 4\}
\]
2. **Set of Vowels in the English Alphabet**:
\[
B = \{a, e, i, o, u\}
\]
3. **Set of Primary Colors**:
\[
C = \{red, blue, yellow\}
\]
These examples illustrate how sets can consist of numbers, letters, or items from a specific category.
