1, historical evolution
The origin of capital letters can be traced back to ancient currency and commercial transactions. In ancient times, in order to prevent numbers from being tampered with or forged, people began to use more complicated capital letters to represent large sums of money. With the passage of time, this writing method has gradually become a norm and has been widely accepted and applied.
2. Cultural significance
Capital letters are not only a way of writing, but also have rich cultural significance. In traditional culture, numbers are usually associated with the concepts of auspiciousness, happiness and good luck. The form of capital letters is not only to prevent numbers from being tampered with, but also to pin people's expectations and blessings for a better future.
3. Practical application
In modern society, although the writing method of numbers has been gradually simplified, capital letters are still widely used in some occasions. In financial reports, contracts and agreements, and important documents, large sums of money or specific figures are expressed in capital letters to ensure the accuracy of figures and prevent misunderstanding.
Brief introduction of Arabic numerals
1, origin and spread
The origin of Arabic numerals can be traced back to India. During the 6th-7th century A.D., Indian mathematician Ayepihite invented a numerical counting method, which gradually spread to the Arab region with the economic and cultural exchanges. In the 9th century, Hua Lazimi improved it and spread it to Europe, gradually replacing the use of Roman numerals.

Arabic numerals are easy to learn and understand. The combination of 10 basic numbers (0, 1, 2, 3, 4, 5, 6, 7, 8, 9) can represent values of any size. In contrast, the Roman numeral system is complex and difficult to calculate, which makes Arabic numerals more popular in business, science and cultural exchanges.
3. Application area
Arabic numerals are widely used in various fields. In scientific research, data used to represent various physical quantities, chemical elements and scientific experiments. In the commercial field, Arabic numerals are used for calculation, statistics and preparation of financial statements.
