Description
The second edition looks more like a standard text book. The number of problems were either increased or reduced at the end of each section. Chapter tests have been added. Informal proofs were used to show why two negative numbers multiplied together or divided together results in a positive number. A polynomial brain teaser was also added. All grammatical, typing and computational errors in the first edition have been corrected. Graphs for this book were created using a free download from http: //www.padowan.dk. The inequality graphs were created using graphmatica.
