### Editorial Reviews

##### Booknews
New edition of a text which introduces mathematical concepts that are used in our contemporary world, relating these ideas to areas such as sociology, business and psychology. The redesigned format provides new examples and exercises, and each chapter contains special features such as a preview, "getting started," "in other words," problem-solving sections, and research questions. Rather than the more abstract and theoretical aspects, the understanding and use of concepts is emphasized. Annotation c. by Book News, Inc., Portland, Or.
