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

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:

Covid policy (required by the University):

Following University policy, all students are required to engage in appropriate behavior to protect the health and safety of the community. Students are also required to follow the campus COVID-19 protocols.

Students who feel ill must not come to class. In addition, students who test positive for COVID-19 or have had an exposure that requires testing and/or quarantine must not attend class. The University will provide information to the instructor, in a manner that complies with privacy laws, about students in these latter categories. These students are judged to have excused absences for the class period and should contact the instructor via email about making up the work.

 Students who fail to abide by these rules will first be asked to comply; if they refuse, they will be required to leave the classroom immediately. If a student is asked to leave the classroom, the non-compliant student will be judged to have an unexcused absence and reported to the Office for Student Conflict Resolution for disciplinary action. Accumulation of non-compliance complaints against a student may result in dismissal from the University.

Academic integrity

Violations of academic integrity will be taken seriously, and will be handled under the procedures of 
Article I, Part 4 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 (
