Ring Arithmetic $mathbb{Z}/nmathbb{Z}$

Definition

Ring Arithmetic mathbbZ/nmathbbZ refers to mathematical operations performed within the ring of integers modulo n. In this system, numbers “wrap around” after reaching n, meaning all results are the remainder when divided by n. This arithmetic is foundational for many cryptographic constructions, including hash functions and zero-knowledge proofs. It provides a finite and predictable mathematical environment. Such arithmetic is essential for cryptographic security.
