Course Description: MAT 333, Abstract Algebra, covers material from the textbook: sets, groups, rings, polynomial rings, fields.

Text: Available on Blackboard. Optional: Algebra I: Groups, Rings, & Arithmetic, by Serban Raianu, PDF available online at https://math.csudh.edu/~sraianu/algebrabook.html

Objectives: After completing MAT 333 the student should be able to: state definitions of basic concepts (e.g., congruence, groups, rings, integral domains, fields, subrings, homomorphisms, ideals); understand and use the Euclidean algorithm; understand and use modular arithmetic; state major theorems (e.g., the division algorithm, the unique factorization theorem, the remainder theorem, the factor theorem, the isomorphism theorems) and be able to identify the structures to which each theorem applies (e.g. the integers, integral domains, polynomial rings F[x] where F is a field, groups, etc.) ; find examples of objects that satisfy given algebraic properties (a noncommutative ring, a commutative ring but not an integral domain, etc)

Prerequisites: MAT 271 or equivalent with a grade of "C" or better.

Grades: Grades will be based on three in‑class full period examinations (60% total), a comprehensive final examination (25%), and quizzes and homework, (15%) for the remainder.

The exact grading system for your section is the following:

Each of the three 80-minutes exams will be graded on a 100 scale, then the sum of the scores is divided by 5 and denoted by E.

WeBWorK:  All homework, quizzes, and exams will be done in WeBWork, which can be accessed at

https://math.csudh.edu/webwork2/20Fall_MAT333-01_Raianu/

Log in with:

User name: the part before the “@” in the email address that you have given to my.csudh.edu

Password: your 9 digit CSUDH student ID

You can change the password after the first log in. If you did not use WeBWorK before, use Set0 to learn how to input your answers (Set0 will not be graded). You should download and print one set, work on the problems, then input your answers. You can use the "email instructor" button to ask for help, in this way I will see the problem you need help with and all your past answers. For all quizzes and tests you will also have to upload your paper work on Blackboard. No credit will be given without the paper work.

Homework will be due every Monday on WeBWorK, and each homework is worth 5 points. No late homework will be accepted. The average of all homework scores is denoted by H.

5 to 10 minutes quizzes will be given in principle every Monday, and will be graded on a scale from 1 to 10. The average of the quizzes scores is denoted by Q.

The final exam will be graded out of a maximum possible 200, then the score is divided by 8 and denoted by F. All quizzes and exams will be taken on WeBWorK.

You will also need to take a picture of your paper work and upload it on Blackboard. No credit will be given without the paper work.

To determine your final grade, compute E+H+Q+F. The maximum is 100, and the grade will be given by the rule:

A: 93‑100; A‑: 90‑92; B+: 87‑89; B: 83‑86; B‑: 80‑82

C+: 77‑79; C: 73‑76; C‑: 70‑72; D+: 67‑69; D: 60‑66; F: Less than 60.

Makeups: No makeup examinations or quizzes will be given. If you must miss an examination for a legitimate reason, discuss this, in advance, with me, and I may then substitute the relevant score from your final examination for the missing grade.

Accommodations for Students with Disabilities: Cal State Dominguez Hills adheres to all applicable federal, state, and local laws, regulations, and guidelines with respect to providing reasonable accommodations for students with temporary and permanent disabilities. If you have a disability that may adversely affect your work in this class, I encourage you to register with Student disAbility Resource Center (SdRC) and to talk with me about how I can best help you. All disclosures of disabilities will be kept strictly confidential. Please note: no accommodation may be made until you register with the SdRC in WH D-180. For information call (310) 243-3660 or to use telecommunications Device for the Deaf, call (310) 243-2028.

Academic Integrity: The mathematics department does not tolerate cheating. Students who have questions or concerns about academic integrity should ask their professors or the counselors in the Student Development Office, or refer to the University Catalog for more information. (Look in the index under "academic integrity".)
