This new edition of a classic American Tech textbook presents basic mathematic concepts typically applied in the industrial, business, construction and craft trades. By combining comprehensive text with illustrated examples of mathematics problems, this book offers easy-to-understand instructions for solving math-based problems encountered on the job. Many different trade areas are represented throughout the book.

Each of the twelve chapters contains an Introduction providing an overview of the chapter content. Examples of specific mathematic problems are displayed in illustrated, step-by-step formats. Following visual as well as written processes provides the reader with a sequenced opportunity to learn each concept. Learned knowledge is then applied in Practice Problems, which immediately follow Examples in the book. Students are encouraged to use the space provided in the margins to answer these questions.

Tips located throughout the text assist in the development of mathematics skills. Calculator tips are also provided in each chapter to offer an alternative method of solving problems and equations. Points to Know are included to enhance the learner’s understanding of how mathematics principles are applied to the trade professions.
