Description

Technical Field

[0001] The present invention relates to the technical field of mathematical calculation tools, and particularly to a vertical calculator. Background Art

[0002] Digital addition, subtraction, multiplication, and division are the basic mathematical skills of primary school students. Currently, in conventional primary school teaching, on the blackboard, teachers use chalk or PPT to demonstrate. When teaching, teachers often draw pictures to help students understand problems, and students practice on their exercise books. This teaching method is rather boring, and students are prone to boredom with learning. At the same time, for the sake of convenient calculation, vertical calculation is usually carried out during the calculation process. During the teaching process, it is often found that primary school students cannot concentrate, have difficulty understanding the process of vertical calculation, and cannot correctly perform addition, subtraction, multiplication, and division operations after class. There are also some primary school students who cannot use vertical calculation. Therefore, teachers currently lack a vertical calculator to assist teaching, enabling primary school students to better understand the courses of vertical calculation. Summary of the Invention
