Hand-brain quick calculation is to use different human organs to simulate the operation of corresponding components and principles of computers, and to simulate computers to develop the computing and counting potential of human bodies. It is realized by simulating the calculation and counting of computer 0 and 1 theory to single digits, and simulating the way (software) of computer inductive processing information. It is not only a calculation method, but also a method to train people's hands and brains to simulate computer rapid operation and counting.
Benefits of learning to calculate quickly by hand and brain:
1, which greatly shortens the learning time. Learning with "finger fast algorithm" is 10 day, which is equivalent to regular learning for half a year. With frequent practice, manual calculation becomes mental calculation, and the calculation speed can exceed that of electronic calculator.
2. Greatly improve children's thinking ability. Mathematics is very abstract. Through the "finger fast algorithm", children can easily understand the composition of numbers within 10 and understand the basic principles of addition, subtraction, multiplication and division, which plays an analogy role for children and develops their thinking ability faster.
3. A method to promote the development of hands and brains, achieve ingenuity, develop intelligence and realize rapid calculation.
4. The combination of left and right hands is beneficial to the development of left and right brain potential and enhances the perception and memory ability of the brain.
5. Cultivate children's interest in learning mathematics.
