Mathematical literacy means that students have learned some knowledge, mastered enough methods and problem-solving ability, and can skillfully use them. If there are problems that need to be solved in real life, students can think about the transformation problem from the perspective of mathematics, and then analyze and solve the problem through mathematical methods, thus cultivating this habit and quality of actively dealing with problems.
The orientation of mathematics literacy is always determined by the performance of mathematics in adult society, including the formulation of "adapting to personal lifelong development" in China's mathematics literacy, which only points to citizens and adults.
Therefore, students' core literacy in the development of mathematics is not reflected in the academic examination results of that year, but in their future adult life and career. For students' sustainable development and adaptation to the rapidly changing future life, it is necessary to improve students' core literacy.
