TEXT: Algebra: Abstract and Concrete, 2nd or 2.5th edition, by Frederick M. Goodman.
OVERVIEW: This is an introductory course in modern algebra. It differs from Math 5285H: Fundamental Structures of Algebra by (i) being less theoretical, and (ii) having somewhat different subject matter. (There are, however, some overlaps in topics covered in the two courses.) The only prerequisite for Math 4281, aside from sophomore level calculus-type courses is Math 2283 or Math 3283W (Sequences, Series, and Foundations) -- either version is acceptable.
PREREQUISITES: Math 2283 or 3283W.
COVERAGE: Sections 1.1 - 1.11; 2.1 - 2.7; 3.1, 3.3; 5.1 - 5.2; 6.1 - 6.4; 7.3; 8.1; 9.1; 10.3 (time permitting).
MAKE-UP TESTS: There will be no make-up tests. However, early tests will be given, if you have a valid reason. If you have to miss an hour exam, your grade on it will be the prorated grade of the following exam. If you have to miss the last exam, the grade on it will be the minimum of your grades on the first and the second exam. If you miss two tests, one of them will be graded as zero. If you miss three, they will all be graded as zero. You have to tell me before the exam (e-mail is fine) that you want to exercise this option and skip the test.
HOMEWORK: Homework will be collected on Monday class meetings and a random selection of problems graded. Every once in a while we will be discussing it in class. Also note that selected homework problems (or similar) may be given on tests. This is another reason why you should do the homework before each class and, moreover, remember the ideas and techniques used in your solutions. Getting together with other students (that is, in study groups) is a very efficient way to do homework (and have fun and pizza).
GRADING POLICY: Grades will be assigned on curve, using the following weights:
CALCULATOR POLICY: No calculators will be allowed on any tests.
