Title: Stupid author
Review: Indeed, the author doesn't show much examples for most of theproblems. The author assumes students know how to solve the problems, therefore, she skips most of the details. This type of math is not very useful in today's society. It's really stupid!This is also an expensive book and it certainly not worth leaning when the author didn't show much details especially for the more difficult problems. She is a stupid, lazy author!
