Google has quietly changed their search engine. When I searched for Arabic numerals, the first thing that came up was this Artificial Intelligence article.
Arabic numerals are the symbols 0, 1, 2, 3, 4, 5, 6, 7, 8, and 9, which are used to represent numbers. They are the most common way to write numbers in the world.
Origin:
Origin:
The numerals originated in India in the 6th or 7th century.
Arab scholars adopted the numerals and introduced them to Europe in the 12th century.
The numerals were developed over thousands of years and benefited from contributions from the Egyptians, Indians, and Arabs.
Uses:
Arabic numerals are used for counting and mathematical operations.

Uses:
Arabic numerals are used for counting and mathematical operations.
They are used in computers, phones, libraries, and to indicate time.
They are also used to write numbers in other bases, like octal.
They are used to write non-numerical information, such as license plate identifiers and trademarks.
Variations:
Eastern Arabic numerals: Used in Iran, Afghanistan, Pakistan, and other countries in the Eastern part of the Middle East.
Western Arabic numerals: Used in Europe, the Americas, Morocco, Algeria, Tunisia, and Libya.
I read it on the computer, so it must be so.

The octal numbering system is a base-8 number system, meaning it uses eight digits (0, 1, 2, 3, 4, 5, 6, and 7) to represent numbers, with each place value representing a power of 8; essentially, it's a way to write numbers using only the digits from 0 to 7, where each digit's position determines its value based on a power of 8.
Key points about the octal system:
Base: 8
Digits used: 0, 1, 2, 3, 4, 5, 6, 7
Place value: Each digit's position represents a power of 8
Example:
The octal number "125" would be interpreted as: (1, 8^2) + (2, 8^1) + (5, and 8^0) = 64 + 16 + 5 = 85 in decimal.
Why is octal useful?
Easy conversion to binary:
Since 8 is a power of 2, converting between octal and binary is straightforward by grouping binary digits into sets of three.
Used in some computer systems:
Octal is sometimes used in older computer systems to represent memory addresses due to its easy conversion to binary.
