Final answer:
Mathematics is not a natural science as it focuses on understanding mathematical relations and calculations, which is distinct from natural sciences.
Step-by-step explanation:
b. No, mathematics is not a natural science. It focuses on understanding mathematical relations and calculations, which is useful in natural sciences but is distinct from them. Natural sciences, such as physics, chemistry, biology, geology, and astronomy, study natural phenomena and use the scientific method. Mathematics, on the other hand, deals with abstract concepts and numerical relationships.
