In a cross-sectional study, 160 students in Grades 2, 4, 7, and 11 were interviewed about their reasoning when solving integer addition and subtraction open-number-sentence problems. The authors ...

Big Number Operations is a Delphi-based project that aims to handle numbers that are too large to be stored as integers. These large numbers, also known as "Big Numbers", are stored as strings and are ...

Construct a Turing machine that subtracts one base 3 integer from another. An input will be of the form X#Y, where X and Y are elements of {0, 1, 2}+. Your Turing machine must be a single tape, one ...

This article presents the results of a 7th-grade classroom teaching experiment that supported students’ understanding of integer addition and subtraction. The experiment was conducted to test and ...

Abstract: Large integer modular multiplication and modular addition/subtraction are basic operations in elliptic curve cryptography (ECC). Traditionally, systolic array was used to implement modular ...
