Definition des Plattformkonzepts,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 (. ∈ ., . ∈ . ⇒ . ∈ .).

Congruence arithmetic,Many questions in arithmetic reduce to questions about remainders that can be answered in a systematic manner. For each integer . >1 there is an arithmetic “mod .” that mirrors ordinary arithmetic but is ., since it involves only the . remainders 0, 1, 2,..., .-1 occurring on division by .. Arithmetic mod ., or ., is the subject of this chapter.
