Technical mathematics is a course pioneered by Allyn Washington, and the seventh edition of this text preserves the author's highly regarded approach to technical math while improving on the integration of technology in the text. The book is intended for a two or three-semester course and is taught primarily to students who plan to pursue technical fields. The primary strength of the text is the heavy integration of technical applications, which aids the student pursuing a technical career by showing the importance of a strong foundation in algebraic and trigonometric math.

Allyn Washington defined the technical math market when he wrote the first edition of Basic Technical Mathematics over thirty years ago. His continued vision is to provide highly accurate mathematical concepts based on technical applications. The course is designed to allow the student to be simultaneously enrolled in allied technical areas, such as physics or electronics. The material in the text can be easily rearranged to fit the needs of both instructor and students. Above all, the author's vision of this book is to continue to enlighten today's students that an understanding of elementary math is critical in many aspects of life.

**Features :**

- NEW! Graphing Calculator. The graphing calculator is used throughout the text in examples and has been more heavily integrated and emphasized than the previous edition, although it is still not required for the course. This integration includes over 140 new graphing calculator screens pictured in the text. Pg. 98
- NEW! Design. A new, more open design is an important improvement and feature of the seventh edition. The more spacious layout allows for additional graphing calculator displays in the margin, which gives students a visual representation of the mathematics. Pg. 110
- NEW! Applications. Over 200 new technical applications have been added to the seventh edition. A hallmark strength of the Washington text, the applications challenge students to apply the mathematics to technically-based problems, reinforcing the relevancy of mathematics in the technical fields. Pg. 256
- NEW! Writing Exercises. The number of writing exercises has been increased by more than 40%. A new graphical icon highlights writing exercises in the text. These exercises reinforce student understanding as they require students to verbalize their answers using words rather than numbers.
- NEW! Word Problems and Solutions. Throughout the text, approximately 70 examples present complete solutions to word problems. These examples are clearly indicated in the margin by the phrase "solving a word problem." In addition, the text includes over 700 word problems within exercise sets. Pg. 257
- NEW! Exercises and Figures. The seventh edition includes over 1,000 new exercises, many of which illustrate technical applications. Over 140 new figures have been added to help students visualize applications and concepts. Pg. 9
- Flexibility of Material Coverage. An important and critical feature to the Washington approach to technical math is the flexibility of the Table of Contents. The chapters of the text are easily adapted to the specific needs of the students as well as the instructor. Certain sections or chapters may be omitted without loss of continuity, and chapters may be reordered for a customized syllabus. Notes and suggestions on how to reorder the organization of the material are contained in the Answer Book.
