Simple reading is one of the basic concepts of arithmetic and a reading method. Read the numbers from left to right according to the arrangement of numbers, for example, 3045002 is read as 3045002. This reading method is used when reading pure decimals or records. It is called simple reading method and can be used to read decimal numbers and non-decimal numbers. There are two reading methods: simple reading method and complex reading method.

Whether Arabic numerals (1, 2,3 ...) or Chinese lowercase numerals (1, 2,3 ...) are easy to be altered and tampered with because of their simple strokes.

Therefore, the numbers on general documents and commercial financial bills should be capitalized in Chinese characters: one, two, three, four, five, land, seven, eight, nine, pick up, hundred and thousand (the strokes of "ten thousand, one hundred and one trillion" are complicated and seldom used, so there is no need to replace them with other words).

Extended data:

First, according to the classification of reading methods

1. Read numbers from left to right according to their rows. For example, 3045002 is pronounced as 3045002. This reading method is used when reading pure decimals or records. It is called simple reading method and can be used to read decimal numbers and non-decimal numbers.

2. According to the number of rows from right to left, taking four digits as a level or three digits as a section, and then reading from left to right, it is called graded reading method or segmented reading method, collectively referred to as complex reading method, which is generally used to read decimal integers.

Second, the historical origin of capital figures

The use of capital figures began in the Ming Dynasty. Zhu Yuanzhang issued a decree because of a major corruption case "Guo Huan case" at that time, which clearly required that the number of bookkeeping should be changed from "one, two, three, four, five, six, seven, eight, nine, ten, ten and one hundred thousand" to "one, two, three, four, five, seven and nine". Later, "Mo" and "Qian" were rewritten as "Bai and Qian", which have been used ever since.

At the beginning of the Daming regime, it was stipulated that every year all ministries, prefectures and counties in China should send accountants to the household department to report the income and expenditure accounts and the amount of money and grain in local finance. The figures between governments at all levels and with the Ministry of Housing must be completely consistent. If there is any mistake, it will be returned and reported again.

Because the place is far from the capital, in order to save time and avoid the pain of business trip, all localities have brought blank account books with official seals. If it is returned, please fill in the corrections at any time. Moreover, because the blank account book is covered with sewing seals, it cannot be used for other purposes, and the household administration department has not intervened.
