A mechanic is a skilled technician who repairs and maintains vehicles and machinery. They use their knowledge of mechanical systems and tools to diagnose and fix problems, perform regular maintenance tasks, and ensure that vehicles and machinery are in proper working order. Mechanics often work in automotive repair shops, manufacturing plants, or as independent contractors. They may specialize in specific types of vehicles or machinery, such as cars, trucks, motorcycles, or heavy equipment. Numerical skills are important for mechanics as they often need to use measurements, calculations, and diagnostic tools to identify and solve mechanical issues.
