1, when discussing problems, I am used to emphasizing definitions (defining concepts) and emphasizing the conditions for the existence of problems;

2. When observing problems, I am used to grasping the (functional) relationship among them, and further considering the global (full space) of multiple factors on the basis of micro (local) understanding;

3. When we know the problem, we are used to generalizing the existing strict mathematical concepts such as duality, correlation, randomness, generality, nonlinearity, periodicity and chaos. For example, we can see that price is the duality of goods, and benefit is the universal connotation of companies.

Mathematical literacy belongs to the comprehensive thinking form of epistemology and methodology, and has the cognitive characteristics of conceptualization, abstraction and patterning. People with mathematical literacy are good at popularizing and applying conceptual conclusions and processing methods in mathematics to understand all objective things, and have such philosophical height and cognitive characteristics. Specifically, a person with "mathematical literacy" often shows three characteristics in the activities of understanding and transforming the world.

More generally speaking, mathematical literacy is a professional habit of mathematicians, and we hope to make our major better, more precise and stricter. It is certainly a good thing to have such excellent professional habits. Of all human practices, conscious practice is much faster than unconscious practice only by natural growth. As long as there is such a strong demand, desire and consciousness, everyone can form a higher mathematical literacy if they persist.
