Files that could be used in teaching Abstract Algebra. Some are also used in other classes, (like the Complex Number files), so the section numbers may not match the sections from Abstract Algebra. As of Spring 2016, I have started using a new Abstract Algebra book. The book by Pinter doesn't include as many concrete examples for students to work with, so I hope to expand the worksheets. I will also have to alter the Chapter number as the course proceeds. If you find what you think is an error, please take a screen shot and email that to me (khopkins@sbuniv.edu) so I can investigate.

Files that have been created or updated (title at least) for Pinter's book used first in Spring 2016

• 1. Appendix-Set Operations
• 2. New Operations
• 3. Z_n Under Addition-An example of operations from Chapter 2
• 4. Z_n Under Multiplication-An example of operations-Chapter 2
• 5. Ordered Pair, Group Example-Chapter 3
• 6. Chapter 7-Permutations
• 7. Chapter 7-Permutations
• 8. Chapter 7-Permutations
• 9. Chapter 7-Permutations
• 10. Chapter 8-Permutations of a Finite Set
• 11. Chapter 8-Permutations of a Finite Set
