Mathematics has important practical significance. Mathematics is like a pearl, shining with human wisdom. For thousands of years, it has attracted countless math lovers to contribute their talents and wisdom on the road of exploring mathematics.
Introduction to the essence of mathematics
It lies in the ability of abstraction, which abstracts complex problems into simple problems or solved problems or problems that can be concluded by machine calculation. It's a pity that foreigners are still laughing at their ignorance of multiplication tables. But the change is actually limited by "arithmetic", which is faster than rote memorization and accurate calculation. And mathematics is a science, focusing on "learning".
The whole culture of China is flawed in this respect, paying too much attention to "technique" and not exploring "learning". So there are so many alchemists who can't be chemists, so many craftsmen who can't be physicists, and even the Pythagorean theorem, which is called the first invention, is just the discovery and rote memorization of "hooking three strands, four strings and five", and fails to sum up the knowledge behind numbers with equal squares.
