Palm calculation-a quick calculation method developed by Niu Hongwei, a teacher in Xi 'an. It is a method of mathematical operation without abacus.
For a long time, people always do calculations by hand or with the help of other calculators (such as abacus, computer, etc.). In fact, every normal person's hand is also a perfect calculator. With the palm of his hand, he can perform six operations such as addition, subtraction, multiplication, division, square and square of multiple digits, and his operation speed (of course, after a certain period of practice) can be comparable to that of electronic computers.
palm calculation-the method of representing numbers is to use five fingers of the left hand as a digital dial, each finger represents a digit, and five fingers can represent five digits.
the number on each finger is 9. First of all, we see that there are three joints on our fingers. From top to bottom, the left side of the middle of the first joint represents 1, the left side of the middle of the second joint represents 2, the left side of the middle of the third joint represents 3, moving down from 3 to the palm represents 4, the upper end of the finger represents 5, and the belly of the finger represents 6. From top to bottom, there are three stripes on the palm, the first stripe represents 7, and the second stripe represents 7.
the calculation method of palm calculation is a method of using mental arithmetic to reproduce the calculation process by using the brain image and get the result. It regards the left hand as a virtual abacus with five gears, and uses the right hand to point to calculate according to this virtual abacus. When counting, use the fingers of your right hand to point the fingers of your left 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. Corresponding professional division of labor does not interfere with each other. Which finger clicks counts, which finger stretches out, and when the finger doesn't click counts, it bends, indicating . Combined with the abacus formula, four operations of addition, subtraction, multiplication and division of any number within 1 thousand digits can be performed.

palm calculation-reduce the complicated calculation process of written calculation formulas, save time and effort, and improve the calculation speed of students. Some educators have applied the palm calculation method to the field of early childhood education. Teacher Niu Hongwei of Xi 'an has been engaged in education for many years. He has taught thousands of children to learn "palm calculation". It has a good effect in inspiring children's intelligence. Palm computing has effectively developed students' brains and stimulated their potential.
Whole Brain Palm Computing-On May 6th, 29, Mr. Niu Hongwei obtained the patent certificate issued by the People's Republic of China and China National Intellectual Property Administration. Patent number; ZL2831164377.。 It is protected by the Patent Law of the People's Republic of China. At present, the method of "palm calculation" has attracted attention from 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 nationwide, with the aim of letting all children learn and master the fast algorithm, quickly improving their academic performance, and laying a solid mathematical foundation for their future studies.
this is patented, and that's all we can know.
