Problems solved by technology

[0003] However, when the existing computer-based mathematics teaching device is in use, because some users need to write on the blackboard, there is more dust in the classroom, and the dust is easy to fall on the display screen, which affects the user's viewing of the display screen. When the user cleans the dust on the display screen, it is wasteful, and it is inconvenient to collect the dust generated by cleaning, which is easy to cause secondary pollution. When the user uses the display screen, sometimes he needs to read books for combined teaching, but Books are easy to turn pages due to the influence of wind or itself, which will affect the user's viewing of the book, and it is inconvenient to increase the comfort of the user when viewing the book
