The origin of mathematics
Mathematics, which originated from early human production activities, is one of the six great arts in ancient China, and is also regarded as the starting point of philosophy by ancient Greek scholars. The evolution of mathematics can be regarded as the continuous development of abstraction and the extension of subject matter.
The first abstract concept is number, and its recognition that two apples and two oranges have something in common is a great breakthrough in human thought. In addition to how to calculate the number of actual substances, human beings also know how to calculate the number of abstract substances.
