<p>TsipaR: </p> <hr /> <div>A '''ring''' in [[mathematics]] is a set ''R'' equipped with two [[binary]] [[operations]], usually called addition and multiplication, satisfying that <br /> <br /> <br /> '''1.''' ''R'' with addition is a [[commutative]] [[group]]; <br /> <br /> '''2.''' ''R'' with multiplication is a [[semigroup]];<br /> <br /> '''3.''' multiplication [[distributes]] over addition.<br /> <br /> <br /> ==Remarks==<br /> <br /> A '''ring with unit''' is a ring for which multiplication has a [[neutral element]].<br /> <br /> A '''division ring''' is a ring such that ''R'' with multiplication is a (not necessarily [[commutative]]) [[group]].</div>
