### 7.2.4 poly (plural)

Polynomials and vectors are the basic data for all main algorithms in PLURAL. Polynomials consist of finitely many terms (coefficient*monomial) which are combined by the usual polynomial operations (see poly expressions (plural)). Polynomials can only be defined or accessed with respect to a basering which determines the coefficient type, the names of the indeterminants and the monomial ordering.
Example:

      ring r=32003,(x,y,z),dp;
      poly f=x3+y5+z2;

Remark: Remember the conventions on polynomial multiplication we follow (`*`-multiplication in PLURAL).
