Fours are a group of numbers that can be classified as integers. The number four is the smallest composite number, meaning it has divisors other than one and itself, specifically 1, 2, 4. In mathematics, it is often represented in various forms, such as in Roman numerals (IV) or binary (100). In many cultures, the number four holds significance. For example, in Chinese culture, it is often considered unlucky because it sounds like the word for "death." Conversely, in Western cultures, it can symbolize stability, as seen in the four cardinal directions: north, south, east, and west.
