Natural number four-bit three-level composite number-level reading demonstrator

Abstract

The invention discloses a natural number four-digit three-level composite number level reading demonstrator, relates to the field of middle and primary school mathematics teaching, teaching research and calculator manufacturing and application, and aims to apply a natural number four-digit four-level grouping method to group natural numbers according to natural number single number levels and composite number levels and read and write numbers according to the natural number four-digit four-level grouping reading method. The theory and method problems of disordered reading of natural numbers inthe teaching and application process are solved, a natural number four-digit three-level composite number level reading demonstrator is characterized by being composed of a bottom plate (1), a digital voice integrated circuit board (2) and a cover plate (3). A bottom plate (1), a digital voice integrated circuit board (2) and a cover plate (3) are sequentially and horizontally placed on a horizontal tabletop from bottom to top and are fixed by nuts with caps through corresponding mounting round holes in four corners, during application, a method and a working principle of any natural number reading which does not exceed one sixteen digits of three composite number levels are demonstrated.

Description

technical field [0001] The invention of a natural number four-digit three-level compound number readout device involves the fields of mathematics teaching in primary and secondary schools, the field of teaching research, the field of calculator design and manufacturing, and the field of computing applications at all levels and industries, aiming to solve the problem of Arabic numerals being imported from the West Since our country, there has always been the problem of random reading and writing, especially to solve the phenomenon of random reading in the working state of software programs in calculators made of chip technology, and to avoid the adverse effects of misreading and random reading on mathematics teaching in primary and secondary schools. Background technique [0002] In the production and life of the workers and peasants and all strata, there have been problems of reading and writing natural numbers since ancient times. In the ten Arabic numerals 0, 1, 2, 3, 4, 5,...

Problems solved by technology

[0003] However, when it comes to specific readings, almost all teachers read 10 as ten. On several 10 yuan banknotes printed and designed by the People's Bank of China, there are correct readings of "ten yuan" and incorrect readings. The pronunciation of "shiyuan" two phenomena

[0004] In ancient my country's four great classics, "The Romance of the Three Kingdoms", "Water Margin", "Journey to the West", "Dream of Red Mansions" and other novels, there are also issues related to reading. When telling the story of Wu Song fighting a tiger in "Water Margin", there is Wu Song in the "Three Bowls But Not the Hill" hotel There are two phenomena of eating eighteen bowls and eighteen bowls before and after. In "Journey to the West", Monkey King flew one hundred and eight thousand miles with one touch. Many people read it as one hundred and eight thousand miles. They think that 108,000 The 0 between the 100,000 digit 1 and the 1000 digit 8 of this natural number needs to be read, and it is read as 108,000 by a calculator. These phenomena and problems that exist in teaching do not have the invention class Visual aids, unable to explain clearly to students and readers
