Abstract
The purpose of this paper is to study the solutions ofr algebraic (homogeneous) equations in projectiven-space counted with multiplicities given by the length of well-defined primary ideals. Hence we need an extension of the algebraic approach to the intersection theory given in [20]. Also, we will prove that our intersection numbers of irreducible components coincide with the multiplicities of the obvious primary ideals in the obvious local ring of the join-variety.
