20以内加减法口算 1.5.0

The ability to do mental math plays a crucial role in learning mathematics. The ages of 3-7 are an important period for establishing a solid foundation in mental math, as it directly impacts a student's future computational abilities. However, children in preschool may make frequent errors in their arithmetic practice due to their young age and immature psychological development. It is important to use scientific methods to improve children's mental math abilities.

By using a gamified approach, this application allows children to learn through play, making the process of learning mathematics enjoyable and effortless. Additionally, the application offers different levels of difficulty to accommodate different skill levels.
