Mathematicians and philosophers have a series of views on the exact scope and definition of mathematics. The development history of mathematics can be traced back to ancient civilizations such as ancient Egypt, Mesopotamia, and ancient India, while in ancient Greece, the handling of mathematics was more rigorous. Since then, the development of mathematics has made small progress until the Renaissance in16th century. Because of the interaction between new scientific discoveries and mathematical innovation, mathematics has accelerated to today. Mathematics has applications in many 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. Mathematics is a universal means for human beings to strictly describe the abstract structure and mode of things, and can be applied to any problem in the real world. All mathematical objects are artificially defined in essence. In this sense, mathematics belongs to formal science, not natural science.
