Mathematics Mathematics is a discipline that studies the concepts of quantity, structure, change, space and information, and belongs to a formal science from a certain point of view.
Mathematics is produced by counting, calculating, measuring and observing the shape and motion of objects through abstract and logical reasoning. In many countries and regions, mathematics has become a part of education. It is applied in different fields, including science, engineering, medicine, economy and finance. Mathematicians also study pure mathematics, which is the substantive content of mathematics itself and does not aim at any practical application.
