The application of the idea of combining numbers and shapes in primary school mathematics is mainly to use the exercises on weekdays, the mid-term and final exams in primary schools, and the math unit exams. Then there are some related topics under the idea of combining numbers with shapes.

A basic question is how many numbers can be found in a graph, and then a corresponding number can be written. This is the most basic topic, and then some topics about the combination of numbers and shapes, as well as some topics about addition, subtraction, multiplication and division, all get a number or a formula by looking at graphs, so this is even a topic about the combination of numbers and shapes.
