3. Ideal (ring theory)In ring theory, a branch of abstract algebra, an ideal is a special subset of a ring. The ideal conceptually generalizes the property of certain subsets of the integers, such as the "even numbers" or "multiples of 3", that the product of any element of the ring with an element of the subset is again in the subset: the product of any integer with an even integer is again an even integer. An ideal is therefore said to absorb the elements of the ring under multiplication.
