Just download the application in the application market and use it as a common calculator after opening it. Click the handwriting button to convert it into vertical calculation, automatically generate each step of vertical calculation, and support gesture scaling.
Features of vertical calculator:
1, simple operation and easy to use.
2. Support addition, subtraction, multiplication and division.
3. Support decimal operation.
4. The result page supports gesture zooming for easy viewing.
5, can judge the cycle decimal, and display the cycle segment.
The reason why we let our children learn vertical operation is only because people think that learning mathematics requires learning calculation first, and learning calculation is obviously an extremely effective tool. In other words, after studying elementary school mathematics for five or six years, I spend a lot of time training every day, and more than 60% of my time dealing with vertical operation and fighting for it.
However, the biggest obstacle to children's vertical operation is that it puts high demands on a child's spatial working memory.
However, due to their lack of experience and theoretical basis, when they are unfamiliar with everything around them, if they have a lot of memory work at this time, they will be highly nervous about all kinds of details, and their minds will be completely controlled by the details and steps they want to remember at present.
