- We note that there are two major differences between fields and rings, that is: 1. Rings do not have to be commutative. If a ring is commutative, then we say the ring is a commutative ring. 2. Rings do not need to have a multiplicative inverse. From this definition we can say that all fields are rings since every component of the definition of a ri...
