## Prerequisite

Math 221 (grade C or above).

## Learning Objectives

The purpose of this course is twofold. On one hand, we explore counting properties and methods related to the natural numbers ℕ, as well as properties and algorithms on graphs and trees. On the other hand, it presents all those properties in a logical fashion, so that we can understand and justify why they are correct. Among the proof techniques that we will use for the purpose, the most important one is “Mathematical Induction”

By the end of the semester students are expected to be familiar with the counting properties and methods related to the natural numbers, as well as properties and algorithms on graphs and trees. Students are also expected to understand and be able to justify why these properties, methods and algorithms are correct.

This course is a 4-credit course, which means that in addition to the scheduled lectures/discussions, students are expected to do at least 9.5 hours of course-related work each week during the semester. This includes things like: completing assigned readings and homework, studying for tests and examinations, preparing written assignments, and other tasks that must be completed to earn credit in the course.

## Textbook

Discrete Mathematics by L. Lovász, J. Pelikán and K. Vesztergombi, Springer, 2003

• This is the course text.  All homework assignments will come from this book.
• The first part of the book, chapters 1-6, deals with counting properties and methods related to the natural numbers ℕ. The second part, chapters 7-15, deal with properties and algorithms on graphs and trees, and some related topics.
• We plan to cover most of the material in parts I and II, following closely the order and logic framework of the textbook.

• Quizzes (10 %), two tests (40 %, with 20% each), a midterm exam (20%) and a final exam (30 %).
• There are 12 regular quizzes scheduled, one per week of class. No quiz is scheduled for a class session that is immediate after a test. Each quiz will be graded on the scale from 0 to 10.
• If you miss an exam, test or quiz, your score for that exam, test or quiz will be a zero.
• The lowest two quiz grades will be dropped when the final total grade is calculated. Hence only 10 out of the 12 quizzes are counted.
 Components Dates Percentage Time allowed Quiz Weekly 10% 10 minutes * (12-2) Test 1 Friday, Feb. 20 20% 90 minutes Midterm Wednesday, Mar. 18 20% 90 minutes Test 3 Monday, Apr. 20 20% 90 minutes Final TBA 30% 120 minutes TOTAL 100%

### Homework Assignment

• Homework will be sent to you via email as well as posted at Homework Page.
• Homework assignments will not be graded. Students are welcome to discuss the homework with the instructor during office hours.

### Quiz

• Quiz problems are chosen from previous homework assignments either in exactly same forms or with some modifications. It is highly recommended that a student finishes homework by him- or herself.
• No make-up is given for missed quizzes.

Note that a “Pass” grade in the “Pass/Fail” grade option does not count toward math degrees. If you are a math major, it is not advised to change the grade option to “Pass/Fail” unless you are ready to retake the course at a later time.

## Make-ups

If you need to take a make-up, if possible, an advance request should be given. Checkable written proof to justify the request should be given.

In order to minimize the need for make-up exams and the stress of dealing with multiple exams, within the first two weeks of the semester, all students must check the exam schedules of other courses they are taking and make sure that there is no major conflict. The exam dates may be changed accordingly only if the instructor determines necessary.
