Nature of Mathematics, 13th edition, by Karl Smith is written for liberal arts students and based on the belief that learning to solve problems is the principal reason for studying mathematics. Karl Smith introduces students to Polya's problem-solving techniques and shows them how to use these techniques to solve unfamiliar problems that they encounter in their own lives. Through the emphasis on problem solving and estimation, along with numerous in-text study aids, students are assisted in understanding the concepts and mastering the techniques. The WebAssign enhancement to this textbook engages students with immediate feedback, rich tutorial content, video instruction, and a full eBook.
