Octal, also known as base-8, has been around for centuries, but it's only now gaining attention in the US due to its growing importance in various fields, such as computer science, cybersecurity, and electronics.

  • Digital electronics: IC (Integrated Circuit) numbers often use octal notation.

    • 80 ÷ 8 = 10, remainder 0

    So, what is octal exactly? Octal is a number system that uses eight distinct symbols: 0, 1, 2, 3, 4, 5, 6, and 7. It's a base-8 system, meaning it uses eight as the base or foundation for counting, unlike our familiar base-10 system, which uses 10.
