4 is a natural number that follows 3 and precedes 5. It is an integer and can be classified as an even number because it is divisible by 2 without a remainder. In mathematics, 4 is significant in various ways, including:
- Arithmetic: It is the result of adding 2 + 2 or multiplying 2 x 2.
- Geometry: A square has four sides and four corners, which is foundational in geometry.
- Real-world examples: We often group items in fours, like four seasons in a year or four cardinal directions (North, South, East, West).
Overall, 4 is not just a number; it represents concepts and divisions in our everyday life and mathematical structures.
