What is the definition of engineering?

The correct choice defines engineering as the application of science and mathematics to solve problems. This definition highlights the core function of engineering, which involves using scientific principles and mathematical techniques to design, create, and optimize solutions for real-world challenges. Engineers draw on knowledge from various scientific fields, such as physics and chemistry, as well as advanced mathematics to innovate and implement efficient systems, structures, and processes.

This understanding is crucial in many engineering disciplines—whether it's civil, mechanical, electrical, or software engineering—since the primary goal is to find effective solutions that qualify as both functional and economically viable. By focusing on problem-solving through the systematic application of scientific and mathematical concepts, this definition encapsulates the essence of engineering work in addressing societal and technological needs.
