## Main Question or Discussion Point

Hi,

I am doing self study with some special attention to number theory with application to computer science. I have Knuth vol1 and Apostol but I am finding Knuth exercises too tough and explanations too short and very less basic material to base proofs on. I find that simply reading Apostol's introductory material throws a lot of light on some of the problems. Does any body else feel the same? Are Knuth's exercises designed so that I have to research mathematics from other books in order to solve them rather than find ideas from his own material? My aim is to learn and write proofs.
