COURSE DESCRIPTION
WHAT IS MATH 100A?
This is the first in a series of three courses in abstract algebra for
students majoring in mathematics at UCSD. In this course we
will examine several topics in group theory. We will
cover most material in Chapters 1, 2, 8 in the textbook. Math 109
(mathematical reasoning) is a strongly enforced background requirement
for this course.
TEXT W. Keith Nicholson Introduction to Abstract Algebra, Fourth Edition.
(Wiley 2012). You
are expected to read the text BEFORE each lecture. The students
enrolled in this class are expected to be familiar with the material
taught in Math 109 (Mathematical Reasoning), which is a strongly
enforced background
requirement for Math 100A. If you need a review in Math 109, you are
strongly encouraged to read on your own Chapter 0 and Section 1.1 in
your textbook and solve some of the exercises within.

CLASSROOM CONDUCT EXPECTATIONS
 Electronic
devices: Please do not use devices (such as cell phones, laptops,
tablets, iPods) for nonclassrelated matters while in class/section.
No visual or audio recording is allowed in class/section without prior
permission of the instructor (whether by camera, cell phone, or other
means).
 Conversations: Please avoid having private conversations with your classmates during lecture and office hours.
 Email
etiquette: I will not discuss mathematics (e.g. solutions or hints of
solutions to HW problems) via email. Office hours and lectures are the
best venue for that purpose. However, if you have any type of
administrative questions regarding this class, please do not hesitate
to send me short and to the point email messages.
GETTING HELP
Help with mathematical problems:
 Section: Ask
questions in section  this is one of the main reasons why sections
exist.
 Office Hours: You
are strongly advised to take full advantage of your professor's and
ta's office
hours.
 Classmates: Sometimes
a classmate can help. Sometimes you can learn by working out problems
together with your classmates.
Help with personal problems which
affect your class work:
 Talk to the professor or, if appropriate, your
college provost.
