Modular Arithmetic (General)
Generic Expression
• A modulo B == C A: ‘dividend’ Modulo = mod = % B: ‘modulus’ ==: Indicates
congruency C: remainder derived
from A/B

Computer Science Algorithm
• Algorithm for Most Programming Languages:1. Quotient = RoundToZero(A/B)
2. Remainder = A – (Quotient * B)

Pure Math
Modular Arithmetic
• -1 mod 4 == …-5, -1, 3, 7… Infinite possible
answers, infinite remainders
Pure Math handles infinite sets

Applied Math
Java Modular arithmetic
• Application limited to finite sets
• Java picks number closest to zero as an ANSWER -1 % 300 == -1 (8 bits) -1 % 300 == 299 (10
bits)
Java Programming Language
