Together with number theory, geometry and analysis, algebra is one of the very cornerstones of modern mathematics. Broadly speaking, it is the study of mathematical symbols and the laws for manipulating them using formulas. This vintage book contains an introductory guide to the subject, walking the reader through its basics and moving on to its practical uses in electrical and steam engineering drawing, as well as machine design and workshop practice. Contents include: "Use of Formulas", "Use of Equations in Solving Problems", "Principles in Algebra", "Solving Equations of the First Degree", "Solving Quadratic Equations", etc. This volume will be of utility to those with an interest in engineering, and it would make for a wonderful addition to allied collections. Many vintage books such as this are increasingly scarce and expensive. We are republishing this volume now in an affordable, modern, high-quality edition complete with the original text and artwork.
