I have completed the first three chapters and am done with the majority of the problems in chapter four. The solutions are in a pdf document that is constantly being updated. I have broken up the document into individual chapters below. The following are all in pdf format.
- Chapter 1: The Fundamental Theorem of Arithmetic (All)
- Chapter 2: Arithmetical Functions and Dirichlet Convolution (All)
- Chapter 3: Averages of Arithmetical Functions (All)
- Chapter 4: Some Elementary Theorems on the Distribution of Prime Numbers (21/30)

Edit: People have been using the solutions to copy them down for assignments rather than to learn from them. As a result, I’m taking them down, at least for now.
