Every AH-subset of R<sub>n</sub>(I) has the form P = ∑<sup>n</sup><sub>i=0 </sub>p <sub>i</sub> I<sub>i</sub>= {a<sub>0</sub>+a<sub>1</sub>I+⋯+a<sub>n</sub>I<sub>n</sub>: a<sub>i</sub>∈p <sub>i</sub>}, where p <sub>i</sub> are subsets of the classical ring R. The objective of this paper is to determine the necessary and sufficient conditions on p <sub>i</sub> which make P be an ideal of R<sub>n</sub>(I). Also, this work introduces a full description of the algebraic structure and form for AH-maximal and minimal ideals in R<sub>n</sub>(I).http://www.journal-fea.com/article_126270_203fe7b5c348152b419438a9298c6da6.pdf
