### A free math course for talented middle school students

The Institute for Mathematics and Computer Science (IMACS) is offering a a series of online math courses for gifted/talented students titled Elements of Mathematics: Foundations . The first of these, Operational Systems, will be FREE if you enroll before January 1, 2013! What is it about? Operational Systems course covers modular arithmetic using secret codes and online games. Learn about operational systems and their properties (commutativity, associativity, neutral elements, invertibility) by building interactive machines and evaluating non-numeric operations. Get a solid introduction to the concepts of least common multiple and greatest common divisor, as well as to the geometric notions of midpoint and reflection. It is a self-study online course, where suitably talented students are able to work independently and at their own pace while still developing a deep understanding of the material. Elements of Mathema
