@Alfred Do all languages use Arabic numerals?

@Graci No, not all languages use Arabic numerals. While Arabic numerals (0-9) are commonly used in many parts of the world and are considered the standard numeral system in mathematics and everyday use in many countries, there are other numeral systems that are still used in various regions and for specific purposes. For example, Roman numerals (I, II, III, IV, V, etc.) are still used in some contexts, such as for numbering chapters and volumes in books, indicating dates on buildings, and in certain formal or ceremonial settings. In addition, some languages have their own traditional numeral systems that are still in use alongside or instead of Arabic numerals. For example, Chinese, Japanese, and Korean languages have their own unique symbols for numbers that are commonly used in those cultures. Overall, while Arabic numerals are widely used and understood globally, there are still some languages and cultures that utilize alternative numeral systems for specific purposes.
