question:
Very intuitive in explaining the basic concepts and the fundamental and widely used methods in continuous-time finance. No deep background in math is required to have a good grasp of this book. I believe it is intuition rather than fancy skills that is important to build up interest and passion for studying a hard topic such as continuous-time finance.
answer:
Positive


question:
I just returned from a month-long trip to Vietnam and Cambodia, and I found this book extremely useful for Cambodia. Not so much for hotel listings, etc., but for no-nonsense background information on Angkor, Phnomh Penh, and Siem Reap. The Vietnam portion was helpful as well, but I relied more on the Lonely Planet and Rough Guide Vietnam editions for that country. I would definitely recommend this book to someone traveling to Cambodia over the Lonely Planet edition, which is *really* outdated.
answer:
Positive


question:
American Electronics Mart sold me a "refurbished" Xerox documate 510 scanner that did not work from the start. I spent two weeks trying to troubleshoot to find out whether the problem was on my end. Then, because I missed the return deadline, they would not take the scanner back. They would not agree to pay the costs to me to ship the scanner back to them. Now, I have wasted $250 on a worthless piece of junk sold to me by these crooks. Don't ever buy anything from these creeps.
answer:

Negative
