This is an advanced textbook designed to build on the foundational skills developed in earlier volumes. This book focuses on applied mathematical concepts that are essential in technical trades such as plumbing, gas fitting, pipefitting, and carpentry. It emphasizes real-world problem-solving, using clear explanations and hands-on examples drawn from actual job-site situations.The content is organized into four major parts:<ul><li>Capacities – Understanding and converting between Imperial gallons, U.S. gallons, litres, and cubic feet. This section also explains how to calculate the weight of water using both metric and imperial systems.</li><li>Pressure and Total Force – Differentiating between pressure and force, converting units like psi and feet of head, and calculating total force on surfaces such as tanks, pipes, and valves.</li><li>Grade and Total Fall – Working with slopes expressed as ratios, percentages, or inches per foot, and applying these forms to calculate the total fall required for piping and drainage systems.</li><li>Trigonometry – Using right-triangle relationships, including the Pythagorean theorem and trigonometric functions (sine, cosine, tangent), to solve for unknown sides and angles in practical field applications.</li></ul>To support different learning needs, the book includes step-by-step examples, illustrations, and trade-focused exercises that strengthen practical understanding. Learners also benefit from online supplements such as video walkthroughs, quizzes, and audio versions of each chapter.

This eBook is an advanced trades math textbook covering capacities, pressure and total force, grade and total fall, and trigonometry. It builds applied math skills for fields like plumbing, steam fitting, and gas fitting.
