International Express SB + WB Elementary 2007 + Student's CD
International Express combines general English with business situations. It gives students the social and functional English they need to work, travel, and socialize. It is for adult professional learners.
Based on Common European Framework (CEF) 'can do' objectives, Total English is the ideal choice for teachers who want a well-organised course with clear learning aims and a wide range of authentic supplementary material. Every level has loads of teacher support material, an exciting DVD with authentic clips from film and TV, and a 'catch up' CD-ROM with extra practice for students who miss lessons.
This book, which presupposes familiarity only with the most elementary concepts of arithmetic (divisibility properties, greatest common divisor, etc.), is an expanded version of a series of lectures for graduate students on elementary number theory. Topics include: Compositions and Partitions; Arithmetic Functions; Distribution of Primes; Irrational Numbers; Congruences; Diophantine Equations; Combinatorial Number Theory; and Geometry of Numbers. Three sections of problems (which include exercises as well as unsolved problems) complete the text.
