A ring is a set R equipped with two binary operations + (addition) and ⋅ (multiplication) satisfying the following three sets of axioms, called the ring axioms R is an abelian group under addition, meaning that: R is a monoid under multiplication, meaning that: Multiplication is distributive with … See more In mathematics, rings are algebraic structures that generalize fields: multiplication need not be commutative and multiplicative inverses need not exist. In other words, a ring is a set equipped with two See more The most familiar example of a ring is the set of all integers $${\displaystyle \mathbb {Z} ,}$$ consisting of the numbers See more Commutative rings • The prototypical example is the ring of integers with the two operations of addition and multiplication. • The rational, real and complex numbers … See more The concept of a module over a ring generalizes the concept of a vector space (over a field) by generalizing from multiplication of vectors with elements of a field ( See more Dedekind The study of rings originated from the theory of polynomial rings and the theory of algebraic integers. … See more Products and powers For each nonnegative integer n, given a sequence $${\displaystyle (a_{1},\dots ,a_{n})}$$ of n elements of R, one can define the product $${\displaystyle P_{n}=\prod _{i=1}^{n}a_{i}}$$ recursively: let P0 = 1 and let … See more Direct product Let R and S be rings.

A ring [R; +, ⋅] that has a multiplicative identity is called a ring with unity. The multiplicative identity itself is called the unity of the ring. More formally, if there exists an element 1 ∈ R, such that for all x ∈ R, x ⋅ 1 = 1 ⋅ x = x, then R is called a ring with unity. igbo palm wine cup
