{wiki=Category:Ideals_(ring_theory)}
In ring theory, which is a branch of abstract algebra, an **ideal** is a specific subset of a ring that has particular properties allowing it to be used in the construction of quotient rings and in the study of ring homomorphisms. \#\#\# Definition: Let \\( R \\) be a ring (with unity, but this requirement can be relaxed in some contexts).
