A detailed instruction on the homework assignments





General Expectations
The Department of Mathematics has a general expectations statement, which we are assumed to follow in this class.

Reading

In this class we use the book

Thomas W. Hungerford, Abstract Algebra, An Introduction, third edition


Brooks/Cole Cengage Learning

The book is really unavoidable, and cannot be replaced with another textbook!




There are, however, many abstract algebra textbooks which may be useful. The books listed below may be difficult to read. However, they contain a huge amount of interesting material, and are useful for those who want to continue further with algebra.



Course Objective


The first and foremost objective is to learn the basic ideas and notions of abstract algebra.

The class is designated as writing-intensive. As a consequence, mathematical writing, and particularly, the writing of clear and correct proofs is a subject of emphasis. This course is a prerequisite for the consequent introduction to abstract algebra course (413). It is among the objectives to build a solid basis for this course.

Prerequisites
A first course in linear algebra (Math 311) and, most importantly, Intro to advanced math (Math 321) or consent.


Grading Policy
The course contains a combination of concepts, ideas and techniques which the students must be able to apply in solving specific problems. Most of these problems require proving or disproving certain statements. Since this is a writing-intensive class, we simultaneously learn how to write mathematical texts.

At the end of the day, your grade will reflect your ability to solve specific problems. This assumes your ability to read and understand the textbook. To understand, in this context, means to be able to create arguments which are similar to those provided in the text. To create an argument, in this context, means to be able to write it down properly. More specifically, the following rules are to be taken.



  • Final exam will count for 30% of the final grade. The exam is cumulative (it covers all the material).
  • Three Quizzes. The average grade for the quizzes counts for 30% of the final grade.
  • Four writing homework assignments count together for 40% of the final grade.
