Definition of a ring in math

WebIn mathematics, a ring is an algebraic structure with two binary operations, commonly called addition and multiplication. These operations are defined so as to emulate and generalize the integers. Other common examples of rings include the ring of polynomials of one variable with real coefficients, or a ring of square matrices of a given dimension. WebIntroducing to Quarter in Math.
