Ideals,This chapter pursues the idea that a number is known by the set of its multiples, so an “ideal number” is known by a set that . a set of multiples. Such a set . in a ring . is called an ideal, and it is defined by closure under sums (. ∈ . ⇒ . + . ∈ .) and under multiplication by all elements of the ring (. ∈ ., . ∈ . ⇒ . ∈ .).
