Suzhou code, also known as grass code, flower code, model code and business code. It was a folk "trade name" in early China. It was born out of the counting system in the cultural history of China, and it is also the only counting system still in use. It was produced in Suzhou, China. Now Hong Kong and Macao markets, time-honored tea restaurants and Chinese medicine shops can still be seen occasionally.

Arabic numerals are composed of counting symbols of 0, 1, 2, 3, 4, 5, 6, 7, 8, 9 * * * 10, which is an international number at present. Arabic numerals were first invented by ancient Indians, then spread to Europe by Arabs, and then modernized by Europeans. Because of the spread of Arabs, it has become a key node in the international use of such numbers, so people call it "Arabic numerals".

Roman numerals are used in Europe before the introduction of Arabic numerals (actually Indian numerals), but they are rarely used now. It came into being later than the numbers in China and Oracle Bone Inscriptions, and even later than the Egyptian decimal numbers. However, its appearance marks the progress of an ancient civilization.

The origin of numbers:

There are two theories about the origin of numbers. First, it originated in China. According to historical records, the emperor of China had thirteen brothers, one of whom invented numbers and then invented heavenly stems and earthly branches.

There is also a saying that numbers originated in ancient India and were not invented by Arabs. Numbers were later mastered by Arabs for business, improved and spread to the west.

Westerners call these numbers Arabic numerals because they first came into contact with Arabs and used these data, mistakenly thinking that they invented them, which has caused this historical misunderstanding. Later, with the wide spread in the world, everyone agreed with the term "Arabic numerals", which made people in many parts of the world mistakenly think that numerals were invented by Arabs.

In fact, it was Arabs who first began to use numbers widely. After it spread to Europe, Europeans liked this convenient and applicable notation very much. Although people later learned the truth, they never corrected it because they were used to it.

The spread of numbers:

In the seventh and eighth centuries, the Arab Empire spanned Asia, Africa and Europe. While the Arab Empire expanded around, Arabs also absorbed the advanced cultures of ancient Greece, Rome, India and other countries and translated a large number of scientific works from these countries.

In 77 1 A.D., an Indian traveler, Maoka, made a long journey to Baghdad, the capital of Abbasid Dynasty of Arab Empire. Maoka dedicated an Indian astronomical work "Sidanta" that he carried with him to the then caliph (king) Mansour.

Mansour cherished the book very much and ordered the translator to translate it into Arabic. Translated into Sindh Sindh Sindh. This book uses a lot of Indian figures. As a result, Indian numbers were absorbed and adopted by Arabs.

Since then, Arabs have gradually given up the original 28 letters as a symbol of calculation, and widely used Indian numerals, and in practice, they have also modified and improved Indian numerals to make them easier to write.

When Arabs got hold of Indian figures, they soon introduced them to Europeans. It was very inconvenient for Europeans in the Middle Ages to use long Roman numerals when counting. Therefore, as soon as the simple and clear Indian figures spread to Europe, they were welcomed by Europeans.

But in the beginning, Indian numerals replaced Roman numerals, but it was strongly opposed by the Pope because it was knowledge from "pagans". But practice has proved that the Indian figure is far superior to the Roman figure.

1202, Italy published an important mathematical book, The Book of Calculations, which widely used Indian numerals improved by Arabs, which marked the beginning of using new numerals in Europe. This book is divided into fifteen chapters.

The first chapter reads: "The nine numbers in India are' 9, 8, 7, 6, 5, 4, 3, 2, 1'. Any number can be represented by these nine numbers and the symbol' 0' called' zero' by Arabs. "

With the passage of time, China printing spread to Europe in the14th century, which accelerated the popularization and application of Indian numerals in Europe. Indian numbers are gradually adopted by all Europeans.

Westerners accepted the Indian figures from Arabia, but ignored the ancient Indians at that time and regarded them only as the achievements of Arabs, so they called them Arabic figures, which have been passed down to this day.
