Basic mathematics, also called pure mathematics, or pure mathematics, specializes in the internal laws of mathematics itself. Algebra, geometry, calculus, and probability theory introduced in elementary and middle school textbooks are all part of pure math.
One of the distinctive features of pure mathematics is that it temporarily sets aside specific content and studies the quantitative relationships and spatial forms of things in pure form. It is in accordance with the internal needs of mathematics, or possible future applications, the study of the mathematical structure of its own internal laws, and does not require a direct connection with the solution of practical problems in other disciplines.
Applied mathematics is growing rapidly. The real world is, after all, the source of mathematical development. Since the 17th century, social development and production needs have been the main driving force behind the development of mathematics. Mathematics can provide tools for other disciplines, make them like a tiger, at the same time, the development of other disciplines will also greatly promote the advance of mathematics, which is an important feature of mathematics.
Newton invented calculus from the need for physics, and in turn, Tigu Brahe discovered Neptune using math. By the time the 20th century rolled around, the manufacture and navigation of jets and spacecraft, the medical equipment of CT scans, and the operational schemes for organizing large-scale wars were all essentially mathematical techniques.
