Much of Modern Algebra involves properties of sets together with operations. In the course on Modern Algebra, we have discussed about two major concepts namely Groups and Rings. Basically Group is a structure which involves a set with a single operation whereas Ring is a structure which involves a set with two operations.  

In the course on Modern Algebra we have covered the basic concepts of group theory and ring theory as extensively as possible for the students at an undergraduate level. This course will serve as a useful tool to any learner who wishes to learn about modern algebra.
