Capitalized numbers are a unique way of writing numbers in China. Use Chinese characters with the same pronunciation as numbers instead of numbers to prevent them from being tampered with. According to textual research, capitalized numbers were first invented by Wu Zetian and later improved by Zhu Yuanzhang. The use of capital figures began in the Ming Dynasty. Zhu Yuanzhang issued the imperial edict because of a major corruption case "Guo Huan case" at that time.
It is clearly required that the number of bookkeeping must be changed from "one, two, three, four, five, six, seven, eight, nine, ten, ten and one hundred thousand" to "one, two, three, four, five, six, nine, ten, one hundred and one thousand". Later, "Mo" and "Qian" were rewritten as "Bai and Qian", which have been used ever since.
Arabic numerals were first invented by ancient Indians, then spread to Europe by Arabs, and then modernized by Europeans. It is precisely because of the spread of Arabs that this number has become the key node that is finally used internationally, so people call it "Arabic numeral".
Arabic numerals consist of 0, 1, 2, 3, 4, 5, 6, 7, 8, 9 * * * 10 counting symbols. Take the position value method, the high position is on the left, the low position is on the right, and the writing is from left to right. With the help of some simple mathematical symbols (decimal point, minus sign, percent sign, etc. ), this system can clearly represent all rational numbers.
The origin of the introduction into China:
Arabic numerals were introduced into China from 13 to14th century. Because there was a number called "abacus" in ancient China, which was easy to write, Arabic numerals were not popularized and used in China at that time.
At the beginning of the 20th century, with the absorption and introduction of foreign mathematical achievements, Arabic numerals began to be used slowly in China, and it was only 100 years since it was popularized in China. Arabic numerals have now become the most commonly used numbers in people's study, life and communication.
