1, abstract ability: get rid of all physical attributes of things and get the thinking process of mathematical research objects. It mainly includes abstracting the relationship between mathematical concepts and concepts from the relationship between quantity and quantity, and abstracting general laws and structures from the specific background of things.

2. Logical reasoning: The proposition that deductive reasoning is established in a large range is also established in a small range, which can only be used to verify knowledge and cannot be used to discover new knowledge. Inductive reasoning is the reasoning that predicts the result through conditions and explores the reason through the result. The result is possible and can be used to discover knowledge.

3. Mathematical model: the process of abstracting realistic problems with mathematical methods, expressing problems with mathematical language, establishing models and solving problems with mathematical knowledge and methods.

Characteristics of mathematical literacy:

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.
