- A ring is a set with two operations, called addition and multiplication, that satisfy some properties of a group123. A field is a ring that is also a group under both addition and multiplication1243. A group is a set with an operation that is associative, has an identity element, and has an inverse for every element3. A field is always commutative under both operations, but a ring may not be245. A division ring is a ring where every non-zero element has a multiplicative inverse, and a commutative division ring is a field5.Learn more:✕This summary was generated using AI based on multiple online sources.

A ring is a group under addition. A field is a group under addition and a group under multiplication. Any further description tends to be more confusing. One big difference is that a ring need not be commutative under multiplication, whereas a field is.
www.physicsforums.com/threads/whats-the-differe…A commutative division ring is a field. Wedderburn's little theorem asserts that all finite division rings are commutative and therefore finite fields.
