A Technological View of Modular Congruences.
John A. Rochowicz · 1997
Many students have difficulty finding remainders instead of quotients in the division of two numbers. Students are too quick to use technology and cannot interpret the output correctly. Moreover, many students are not accustomed to doing different yet applicable mathematics. As with all branches of mathematics, modular arithmetic and congruences are useful in real life situations. The use of technology allows students to focus on meanings and apply practice concepts. This paper describes various ways to compute modular congruences on a spreadsheet. Macros are discussed that provide the user with automatic computation of congruence. A drill for the practice of calculating congruences is also included.
