Is A Ring Closed Under Multiplication at May Myers blog

Is A Ring Closed Under Multiplication. but a ring is not a group under multiplication (except for the zero ring), and if we don’t insist that f(1) = 1 as part of a ring. multiplication is no longer assumed commutative (that is it can hold that xy 6= yx for some x;y 2 r) and we have to add. a ring is a nonempty set r with two binary operations (usually written as addition and multiplication) such that for all a;b;c 2 r ,. a ring is a set equipped with two operations (usually referred to as addition and multiplication) that satisfy certain. If \(a, b \in s\text{,}\) then \(a \cdot b \in s\text{.}\) i've looked at a couple sources and neither of them state that rings are closed under addition and multiplication. \(s\) is closed under multiplication:
