Review title: As abstract as it gets....
Product review: This text was required for my Complex Variables course and no one in the class thought it was very helpful. The author is very abstract about concepts, gives no solutions to answers, and doesnt do that great of a job at explaining his points. This isnt even a real textbook! The only positive about this book is it is the cheapest book I have ever bought for college....
