Therefore, even if you can't understand the words written by people from another country, you can still understand the numbers contained in them without translation. It is a miracle that people use at least hundreds of languages in the world at present, but the same number is used in statistics.
But you should know that this knowledge was not achieved at the beginning. The counting system used by humans in the early days is actually as varied as words. To understand why Arabic numerals are widely used all over the world, we should first look at how people counted them in several early civilizations.
On the other hand, the Arabic numerals we use now are the result of this preference. Decimal system is adopted, with simple strokes and convenient writing. Compared with other notation, it has incomparable advantages. A brief summary is as follows:
(1) is concise and easy to understand. This can be seen by comparing 387 with the Roman numeral CCCLXXXVII.
(2) Only a limited number of symbols can express all natural numbers. For notation that is not a numerical system, more symbols need to be introduced to represent large numbers. For example, in order to express numbers above 1000 in Roman numerals, in the Middle Ages, people drew a horizontal line on V, X, L, C, D and M, indicating that V, X, L, C, D and M were multiples of 1000.
(3) Simple calculation, which is perhaps the most important advantage of Arabic numerals. Now ordinary primary school students will use Arabic numerals to do addition, subtraction, multiplication and division. And if a well-trained Roman can do simple addition and subtraction, then a Roman who can multiply and divide can be called an expert.
Logically speaking, the decimal notation of Arabic numerals is adopted, which combines the advantages of Greek alphabet notation and China notation. But in history, it is generally believed that it originated in paramita, India, and was formed after centuries of evolution.
Around 600 AD, paramita was recorded in the value system. At about the same time or later, Indians introduced zero as a number, forming a complete system. At the end of the 8th century, this counting system was introduced to Arab countries. Manuscripts of Indian mathematicians involving Indian numerals were translated and copied by Arabs in the 10 century and introduced into Europe. At this time, the shapes of these numbers have changed greatly, and thus the name of "Arabic numerals" has been obtained. Although adopting new figures has many advantages, there are also many obstacles. It was another four or five hundred years before Arabic numerals were freely used in Europe.
In the next 500 years, Arabic numerals spread all over the world and were used by countries all over the world.
I hope it can help you solve the problem.
