Equations and Inequalities : Elementary Problems and Theorems in Algebra and Number Theory

This is a translation of a successfeul Czech book with more than 1000 problems. The problems can be used to prepare for the International Mathematical Olympiads or the Putnam exam (a prestigious math competition). Each topic contains brief theoretical discussions that are immediately followed by carefully worked out examples of increasing degrees of difficulty, and by exercises which range from routine to rather challenging problems.
