1: The author should learn elementary arithmetic before writing
I am appalled at the author and the editorial board of the publisher.Look at tables 1-1 and 1-2 for example. According to the author, the population of the U.S.A. in 1990 was 76.391 billion (=76,391 billion!!!!). And the GDP was 312.8666 Trilluion dollars (=$312,866 billion dollars!!!). Same blunders about other countries in the table 1-1. Table 1-2 has similar BLUNDERS!!!! I have not had the time to go beyond chapter 1. The author did the greatest disservice to students and other teachers by writing this book, because some teachers will "accidentally adopt it, before they and their students discover that this book is simply a puiece of garbage!
