Required Text:
Introduction to Abstract Mathematics (Donaldson and Pantano)

Please make sure that you have the version of January 21, 2020.

Please get a hard copy at the Illini Union Bookstore.  It costs about $10 and it's very helpful to be able to make notes in the book!

We will cover all of the topics in this book and will cover other topics during the last month of class.

Course Description:
This is an introduction to mathematical language, rigorous mathematical thinking, fundamental mathematical structures, and methods of proof. 
Topics include logic, set theory, induction, equivalence relations, functions, number theory, cardinality, and convergence.

The final grade will be computed based on these percentages:

We will not "curve" the final averages down. For example, if your final average is 80% then your final grade is guaranteed to  be some sort of "B".

It is possible that averages may be "curved" up.  Information about grade distribution will be provided during the semester, and the precise function which assigns a letter grade to each percentage will be determined at the end of the course. 


Class attendance:

Academic integrity
Violations of academic integrity will be taken seriously, and will be handled under the procedures of the student code.

If there are questions about these policies, please don't hesitate to bring them up.

Resources for students with disabilities:
To obtain disability-related academic adjustments or auxiliary aids, students with disabilities should contact the course instructor and Disability Resources and Educational Services (DRES). 
To contact DRES, you may visit 1207 S. Oak St., Champaign, call 333-4603, e-mail or go to the DRES website.

Support resources and supporting fellow students in distress
     As members of the Illinois community, we each have a responsibility to express care and concern for one another. If you come across a classmate whose behavior concerns you, whether in regards to their well-being or yours, we encourage you to refer this behavior to the Student Assistance Center (333-0050) or online at Based upon your report, staff in the Student Assistance Center reaches out to students to make sure they have the support they need to be healthy and safe.
     Further, we understand the impact that struggles with mental health can have on your experience at Illinois; significant stress, strained relationships, anxiety, excessive worry, alcohol/drug problems, a loss of motivation, or problems with eating and/or sleeping can all interfere with optimal academic performance. We encourage all students to reach out to talk with someone, and want to make sure you are aware that you can access mental health support at the Counseling Center ( or McKinley Health Center (
