base-9
- Definition: Base-9, also known as nonary, is a numeral system that uses nine distinct digits, ranging from 0 to 8. Each digit’s position represents a power of 9, with the rightmost digit representing 9^0, the next representing 9^1, and so forth.
- Symbol: The digits used in base-9 are: 0, 1, 2, 3, 4, 5, 6, 7, 8.
- Usage: Base-9 is not commonly used in everyday arithmetic but can be found in certain mathematical contexts and computer science applications where compact representation of data is necessary.
base-12
- Definition: Base-12, also known as duodecimal, is a numeral system that uses twelve distinct digits, from 0 to 11. The digits beyond 9 are typically represented as A (10) and B (11).
- Symbol: The digits used in base-12 are: 0, 1, 2, 3, 4, 5, 6, 7, 8, 9, A, B.
- Usage: Base-12 has historical significance in trade and measurement systems, such as in a dozen or a gross, and is occasionally used in mathematical calculations.
Origin of the base-9
- Base-9 originates from the need for compact numeral systems that can represent large sets of values without using excessive digits. Its development is often associated with ancient counting systems, where the natural counting of objects led to the use of systems based on the number of fingers or other natural groupings.
Origin of the base-12
- The base-12 system has ancient roots, often traced back to the Sumerians and other early civilizations that used duodecimal counting for trade and measurement. The prevalence of 12 in commerce, such as a dozen eggs or a gross of items, highlights its practical utility in human activities.
