Description. This course provides an introduction to the theory of rings, which can be regarded as generalizations of the set of integers, with multiplication and summation.
Schedule. This course consists of two parts and about 25 lectures. We will start by recalling some arithmetic in the set of integers. The first part will end up with the definition of abstract rings. In the second part, we will focus on the study of rings of polynomials.

- Midterm 2: Wednesday of week 7, Feb 22, during the regular class hour.
- Final Exam: Thursday, Mar 23, 2017, 11:30am-2:30pm.
Grading. There are two possibilities for the final grade:
- 10% Homework + 30% Best of the two midterms + 60%Final Exam.
- 10% Homework + 25% Midterm 1 + 25% Midterm 2 + 40% Final Exam.
Academic integrity. Please review the regulations at the following website: http://www.deanofstudents.ucla.edu/Student-Conduct
- Textbooks, Calculators, laptops and cell phones are prohibited during the Midterms and the Final Exam.
- There will be no make-up test. A missed test will count for a zero for that test.
- Students may work together to solve homework problems, but each student must write down his/her own solutions on separate copy. One should also write down the names of his/her collaborators.
- Exam grading complaint should be submitted to the instructor, no later than two weeks after the exam, and before the last lecture.
