Palmistry calculation is a fast calculation method invented by Niu Hongwei, a teacher in Xi 'an. It is a mathematical operation method without abacus.
For a long time, people always calculate by hand or with the help of other calculators (such as abacus and computer). In fact, every normal person's hand is also a perfect calculator. He can use the palm of his hand to perform six operations of adding, subtracting, multiplying, dividing, squaring, etc. The operation speed (after a certain period of practice, of course) can be comparable to that of an electronic computer, and the ratio of multiplication and division can be comparable to it.
Palmistry calculation-the method of representing numbers is to use five fingers of the left hand as a digital dial, each finger represents a number, and five fingers can represent five numbers: one, ten, hundred, thousand and ten thousand.
The number on each finger is 9. First, we see three joints on our fingers. From top to bottom, the left side of the first joint stands for 1, the left side of the second joint stands for 2, and the left side of the third joint stands for 3. From 3 to 4, the upper end of the finger stands for 5, the pulp of the finger stands for 6, and there are three horizontal bars on the palm. From top to bottom, the first bar represents 7 and the second bar represents 7.
The calculation method of palm calculation is a method to reproduce the calculation process by using brain images and mental arithmetic, and get the results. It regards the left hand as a virtual abacus with five gears, and clicks the virtual abacus with the right hand to calculate. When counting, point the fingers of your left hand with the fingers of your right hand. Its clear division of labor is: right thumb/left thumb, right index finger, left middle finger, right ring finger, left ring finger and right little finger. The corresponding professional division of labor does not interfere with each other. Which finger is clicked, which finger is extended, and which finger is not clicked, bending, indicating 0. Combined with the abacus formula, four operations of addition, subtraction, multiplication and division of any number within100000 digits can be performed.

Palm calculation-reduce the complicated calculation process of pen calculation formula, save time and effort, and improve the calculation speed of students. Some educators have applied the palm computing method to the field of preschool education. Teacher Niu Hongwei of Xi 'an has been engaged in education for many years. He has taught thousands of children to learn palmistry. It has a good effect in inspiring children's intelligence. Palm computing has effectively developed students' brains and stimulated their potential.
On May 6th, 2009, Mr. Niu Hongwei obtained the patent certificates issued by People's Republic of China (PRC) and China National Intellectual Property Administration. Patent number; ZL200830 1 164377。 . Protected by the Patent Law of People's Republic of China (PRC). At present, the method of "palm calculation" has attracted the attention of both inside and outside the province and abroad, and many scholars have come to Xi 'an to study. At present, Niu Hongwei's fast algorithm is popularized all over the country. The purpose is to let all children learn and master the fast algorithm, improve their academic performance quickly, and lay a solid mathematical foundation for future study.
This is patented, and that's all I can know.
