[0002] Mathematics is a discipline that studies concepts such as quantity, structure, change, space, and information. From a certain perspective, it belongs to a kind of formal science. Mathematicians and philosophers have a series of views on the exact scope and definition of mathematics. The basic tools necessary for modern human science and technology; the display board is a display device for teaching, which is widely used and favored by relevant teaching staff in various places such as schools and enterprises related to mathematics teaching, and the current market The height of the display boards shown above is fixed and cannot be adjusted. It is inconvenient for students in the back row of the classroom to watch, thus reducing the teaching efficiency. Therefore, there is an urgent need for a height-adjustable display board for mathematics teaching to meet the needs of teaching. use
[0003] Mathematics is particularly computationally intensive. Many times, a panel is exhausted before a problem is solved. Most teachers erase the previous calculation steps and continue to write down. For many students, they still don’t understand Thorough, reducing teaching efficiency
