Hailed by The New York Times Book Review as "...nothing less than a major contribution to the scientific culture of this world," this major survey features the work of 18 outstanding mathematicians. Primary subjects include analytic geometry, algebra, ordinary and partial differential equations, the calculus of variations, functions of a complex variable, prime numbers, and theories of probability and functions. Other topics include linear and non-Euclidean geometry, topology, functional analysis, and more.

This teacher's text accompanies a complete children just beginning to learn English. It uses a careful grading of language and content and introduces pupils to English through a variety of songs and activities.

"Get Ready" - это подготовительный курс к отечественным и зарубежным учебникам. Курс "Get Ready" рассчитан на детей, не знакомых с латинским алфавитом. Он укомплектован специальным пособием по елементарной арифметике (Numbers Book) и набором карточек с изображением разных предметов (Picture Flashcards) и слов (Word Flashcards).

This workbook will improve and expand on the skills acquired in My Book of SIMPLE SUBTRACTION. In this book, children will practice first how to subtract the numbers 1 through 9 and then they will reinforce this skill by learning how to subtract numbers 1 through 20. The purpose of this book is to prepare children for higher-level mathematics by improving their basic subtraction skills.

This workbook will help your child develop an understanding of subtracting the numbers 1 through 5 from whole numbers up to 20. By using this book, children will be able to understand the concept of subtraction by repeatedly tracing and reciting numbers both forwards and backwards and then gradually shifting to subtracting the numbers 1 through 5.

This text is a practical course in complex calculus that covers the applications, but does not assume the full rigor of a real analysis background. Topics covered include algebraic and geometric aspects of complex numbers, differentiation, contour integration, evaluation of finite and infinite real integrals, summation of series and the fundamental theorem of algebra. The Residue Theorem for evaluating complex integrals is presented in such a way that those wishing to study the subject at a deeper level should not need to unlearn anything presented here. A working knowledge of real calculus is assumed as is an acquaintance with complex numbers. This will be of interest to undergraduate students of applied mathematics, physical sciences and engineering.
