Base 7 to Base 18

base-7

• Definition: Base-7, also known as septenary, is a numeral system that uses seven distinct digits: 0, 1, 2, 3, 4, 5, and 6. Each digit’s position represents a power of seven.

• Symbol: The base-7 numeral system does not have a unique symbol but is commonly represented by the numeral “7” in mathematical contexts to denote its base.

• Usage: Base-7 is not widely used in everyday life but can be found in certain mathematical applications and computer science scenarios where systems with a limited number of states are analyzed.

base-18

• Definition: Base-18, or octodecimal, is a numeral system that employs eighteen distinct digits, consisting of 0-9 and the letters A, B, C, D, E, and F to represent values ten to fifteen, respectively.

• Symbol: Similar to base-7, base-18 does not have a distinctive symbol but is represented by the numeral “18” to indicate its base in mathematical terms.

• Usage: Base-18 is primarily used in specialized mathematical contexts, including certain areas of computer science and cryptography, where a larger range of digits can be advantageous.

Origin of the base-7

• Base-7 has its origins in ancient counting systems. It is theorized that early civilizations may have utilized this base due to the number of fingers on one hand. The concept of base-7 has been explored in various mathematical studies, showcasing its unique properties and potential applications in theoretical frameworks.

Origin of the base-18

• Base-18 emerged from efforts to expand numeral systems beyond the more commonly known bases such as binary (base-2) or decimal (base-10). It was developed for use in mathematical theories and applications that require a more extensive range of digits, especially in the realms of computing and data representation.
