Hand-brain quick calculation can make children aged 4- 13 quickly add, subtract, multiply, divide and check any number. It is 5- 10 times faster than other fast calculations, and the speed can exceed that of calculators. At the same time, it can make the left and right brains develop in a balanced way and effectively develop the potential of the whole brain. It is not only a quick calculation, but also a carrier, achieving the purpose of developing the whole brain potential, improving learning ability and cultivating good study habits. The teaching materials are closely related to the new curriculum standards of primary schools and pay attention to the connection between young and old.

At the same time, scientifically applying the characteristics of children's pedagogy, psychology, physiology and children's activeness, fun, curiosity and sensory cognition, integrating interesting mathematics and multiple intelligences, while developing the whole brain, further expanding thinking and memory is more suitable for tapping the potential and personality development of children aged 4- 13.
