1. Highly abstract. The abstraction of mathematics is very prominent in higher mathematics. Number one? Only "number" and "shape" are kept in mathematical abstraction? Abandoned everything else? Second? The abstraction of mathematics is formed through a series of stages? The degree of abstraction it achieves greatly exceeds the general abstraction in natural science.
2. The logic is strict. Every definition and theorem of mathematics? Only after strict logical proof? It can be established in mathematics. And there is a strong consistency between concept and theory.
3. Wide applicability. Like what? Use the concept and law of function derivative? Describe speed and density in physics and marginal cost in economics. The wide application of advanced mathematics is obvious.
2).19101012. Hua was born in Jintan County, Jiangsu Province. He comes from a poor family and is determined to study hard. When I was in middle school, in a math class, the teacher gave the students a famous question: "There is a number, three places, and two;" 5 digits, 5 numbers, and the remaining 3; There are seven places in seven, and there are two left.
