Multiplication of binomials is similar to multiplication of monomials when using the algebra tiles . Some Binomial numbers' underlying binomials have Aurifeuillian factorizations, which can assist in finding prime factors. It is the generalization of the binomial theorem from binomials to multinomials. Substituting minus for plus in "both" the quadratic binomials also results in split-quaternions. Such "polynomial names" may sometimes look like binomials, but are significantly different. The method is most commonly used to multiply linear binomials. Some irreversible binomials are used in legalese. The unconditional distribution is two independent binomials, one for each color. Not all irreversible binomials are bicolons or tricolons, however. Such duplication of binomials occurs in at least six instances. There are many binomials in "Spartium" that are of dubious validity (see below). These binomials could serve as a label to refer to the species. Irreversible binomials generally consist of only a few words at most. They may also be called simply binomials. Many of the "Gymnostoma" species combinations of names (binomials) were described by him in 1982.
