Micro economy covers a great and important place in economics because it builds foundation for all branches of economics. Also it is observed that the weight of mathematics in economy is expanding day by day. Academical searches, journals, books complex mathematical descriptions of economic theories so that nowadays it is not possible to think economy and mathematic apart from each other.This book is not suitable and useful for scholars who is learning economics but useful for searchers who is interesting in mathematical applications of micro economics. In other words this is not a micro economy lesson book, but a testbook for micro economy problems. For that reason readers of this book must know micro economy and mathematic very deeply. Unless readers don’t know economy and mathematic, it is not possible to understand problems and solving methods of them.As you can understand this book is not a lesson book but a testbooka guide for searchers who are looking for different questions about micro economics. First chapter targets to remind mathematical substructure that is needed to solve questions in following chapters. Second chapter includes questions about cardinal and ordinal utility functions, consumer equilibrium.
