Usually we reduce things to the "simplest" terms for display -- saying $0$ is a lot cleaner than saying $1-1$ for example. Unique factorization was a driving force beneath its changing of status, since it's formulation is quickier if 1 is not considered a prime; but I think that group theory was the other force. the number 1: 2. 31). e. It is the smallest positive integer, and smallest natural number. 1 is the multiplicative identity, i. This means that every non-$0$ element has a multiplicative inverse, and that inverse is unique.
