Webmathematics, the science of structure, order, and relation that has evolved from elemental practices of counting, measuring, and describing the shapes of objects. It deals with logical reasoning and quantitative calculation, and its development has involved an increasing degree of idealization and abstraction of its subject matter.

Indeed this is the natural definition of the ring Zn. 2.In the ring R[x] of polynomials with real coefficients, the set x2 +1 := f(x2 +1)p(x) : p(x) 2R[x]g is an ideal whence we obtain the factor ring R[x]. x2 +1 from our motivational example.
