Various topics from number theory and modern algebra, usually including most of the following: Primes and factorization, Diophantine equations, congruences, quadratic reciprocity, continued fractions, rings and fields, finite groups, introduction to arithmetic of the Gaussian integers and quadratic fields. Motivation and examples for the concepts of abstract algebra are derived primarily from number theory and geometry.

Both Postscript and PDF are specialized languages for describing printable documents. Postscript is the older one, and it has traditionally been used to distribute electronic versions of mathematical texts.
Readers for both formats are available for several operating systems and platforms. You can learn more about Postscript here. PDF stands for "Portable Document Format" and it has been developed by Adobe. You can get free readers from their website.
Note that if you download and install Ghostscript you get both a Postscript and PDF reader.
