Modular arithmetic is a system of arithmetic for integers, where numbers wrap around upon reaching a certain value called the modulus. This system is fundamental to many areas of mathematics, ...

This project implements a modular arithmetic calculator using a Finite State Machine (FSM) architecture in PHP. The main goal is to compute the remainder of a number (in any base ≤ 10) modulo a given ...

This paper discusses the use of residue (single and multiple modulus) arithmetic in computing the Moore-Penrose pseudoinverse of a matrix. The process can ...

One of my fellow contributors here recently wrote a post about leap years and why we have them. This reminded me of modular arithmetic and the formula for calculating the day of the week for any date ...

A fundamental challenge in zero-knowledge proof systems is implementing operations that are “foreign” to the underlying constraint system, in that they are arithmetic operations with a different ...
