Number Theory

At Fredonia, we offer this course every other spring semester, and I have taught it several times. In developing the course, I decided to use the theme, "Solving Equations over the Integers or the Integers Modulo n."

Please refer to the attached files.

Chapter 1: Solving Linear Equations Over the Integers

Chapter 2: Solving Linear Congruences

Chapter 3: More on the Integers Modulo n, Including Primitive Roots

Chapter 4: Squares Modulo n

Chapter 5: Pell's and Related Equations

Chapter 6: Fractions
