Theory of Numbers
Course Information, Fall 2008
Here is a list of some practice problems. Note that it is not an exhaustive accounting of examinable topics, but is only intended to give extra practice on some of the key ideas and theorems covered in the course.

Important information about the course, as well as any updates, will be posted to the website.
Math 3070 is intended to be a first course in the theory of numbers, serving as an introduction to the subject. In this course, we will discuss the major theorems in elementary number theory and examine the diversity of problems in the field. It is expected that you are familiar with basic proof techniques such as mathematical induction. Knowledge of calculus is an asset but not required.
We will cover the following topics
- Primes, divisibility, gcd, and the Euclidean algorithm
- Congruences, modular arithmetic, and the Chinese Remainder Theorem
- Wilson's Theorem, Fermat's little Theorem, and Euler's Generalization
- Higher order congruences and primitive roots, quadratic reciprocity
- Cryptography, primality testing, and factoring
- Continued fractions and Pell's equation
- Other topics of interest: partitions, analytic number theory, summation techniques, etc.
The course grade will be determined as follows:
| Homework || 15% |
| Midterms || 25% x 2|
| Final exam|| 35% |
| Total || 100% |
Your final grade will be determined using the following grading scale (slightly modified from the default Faculty of Science conversion scheme):
| Score || 90-100 || 85-89.9 ||80-84.9 ||76-79.9 ||72-75.9 ||68-71.9 ||65-67.9 ||62-64.9 ||58-61.9||50-57.9 || below 50 |
| Grade || A+ || A ||A- ||B+ ||B ||B- ||C+ ||C ||C-||D || F |
Homework will be assigned weekly and will be worth 15% of the course grade. The lowest homework score will be dropped.
Homework 1 is due Tuesday September 16.
Homework 2 is due Thursday September 25.
Homework 3 is due Thursday October 2.
Homework 4 is due Thursday October 23.
Homework 5 is due Thursday October 30.
Homework 6 is due Thursday November 27.
There will be two midterm exams worth 25% each, to be given in class on Tuesdays October 7 and November 4. There will be no make-up exams except in very exceptional cases.
Solutions to Midterm 1.
Solutions to Midterm 2.
The Final Exam:
The final examination will be worth 35% of the course grade and will cover everything in the course. It will be held on Friday December 5 at 3:30 PM. There will be no make-up exams except in very exceptional cases. If your final exam score is higher than your lowest midterm score, the final exam score will replace that midterm score in the calculation of your final grade.
