From the text: This chapter attempts to link the students' world of shopping, curiosity and music to modular arithmetic, trigonometry and complex numbers. It is hoped that the busy teacher will find here ideas to enliven classwork and use the students' natural curiosity as a pedagogical tool in the exploration of numbers. In the world today we rely for many things on digital information. Without digital storage there would be no such thing as a CD or a DVD, satellite television or an mp3 player. NASA would not have been able to receive pictures from Mars. Mobile phones would not work. Information stored in digital form can, indeed will, become corrupted. This leads to errors in the information stored or transmitted. This article is about the two processes of first detecting and then correcting these errors.
