The international edition of this book may be slightly different from the domestic edition. But even if it is, you should be able to find the information you need with only a tiny bit of hunting around.
The answers are given only for odd numbered questions. (Please don't yell at me for only giving odd numbered answers! Many instructors do not want all answers available, and that seems reasonable to me.) My answers may differ slightly from yours, depending on the number of decimal places each of us carried. Do not worry about small differences. I do not give answers for "Discussion questions," because those are really meant for discussion and giving the answers would be self-defeating.
The answers are presented in pdf files. This means that you will need a pdf reader, but most computers will have one installed. If you don't have one, you can download one for free from http://www.adobe.com/products/acrobat/readstep2.html.
