Three (number)

The number three is a natural quantity representing a count of three items or units. It is the integer following two and preceding four. In everyday life, it often appears in contexts such as a trio of objects, three days, or three points in a shape. Mathematically, three is a prime number, meaning it can only be divided evenly by 1 and itself. It is fundamental in various fields, including geometry (a triangle has three sides), calendar systems (weeks usually have seven days, but some focus on three core segments), and symbolic representations (like the concept of the "three main virtues").
