Small design, great acceleration!
This application eliminates the steps of writing answers in oral arithmetic, because it takes time to write answers, and this time can be used to do more oral arithmetic questions.
It is conservatively estimated that at least one second of writing time will be saved for each oral calculation, and at least hundreds to thousands of arithmetic problems will be done after a semester, which will accumulate a considerable number.
