This book, consisting of four chapters, contains 145 problems in mathematical analysis. The topics covered are: metric and topological spaces, series of numbers, sequences and series of functions, functions of more than one variable. Each chapter is divided into four parts: definitions and basic results (I), solved problems (II), additional problems (III), hints and answers for additional problems (IV). There is a table of contents, bibliography and an index, which permit easy location of a special topic and also a quick access to the hints and solutions. The book is mainly addressed to undergraduate students in mathematics as a companion and complement to the basic course in Mathematical Analysis, but may also be a valuable tool for the undergraduate and graduate students in engineering, computer science, economics and the natural sciences.
