28 Number System

The base-28 number system, also called the octovigesimal system, is a positional numeral system that uses twenty-eight symbols: 0, 1, 2, 3, 4, 5, 6, 7, 8, 9, A, B, C, D, E, F, G, H, I, J, K, L, M, N, O, P, and Q, where A represents ten, B eleven, C twelve, D thirteen, E fourteen, F fifteen, G sixteen, H seventeen, I eighteen, J nineteen, K twenty, L twenty-one, M twenty-two, N twenty-three, O twenty-four, P twenty-five, and Q twenty-six in decimal. Each digit’s position represents a power of 28, starting from $28^0$ at the rightmost digit and increasing to the left. For example, the base-28 number 3Q7 equals $3 \times 28^2 + 26 \times 28^1 + 7 \times 28^0 = 2352 + 728 + 7 = 3087$ in decimal. Base-28 is primarily used in theoretical mathematics, number theory, and educational contexts to explore alternative numeral systems, positional notation, and arithmetic patterns. Understanding base-28 allows learners to perform arithmetic operations, convert numbers between bases, and analyze properties of non-decimal systems. Although rarely used in computing or everyday applications, studying the octovigesimal system enhances logical reasoning, problem-solving skills, and comprehension of abstract number representations. It also provides a foundation for higher-level numeral systems and theoretical mathematics.

-22 Number System

The base-22 number system, also called the duovigesimal system, is a positional numeral system that uses twenty-two symbols: 0, 1, 2, 3, 4, 5, 6, 7, 8, 9, A, B, C, D, E, F, G, H, I, J, K, and L, where A represents ten, B eleven, C twelve, D thirteen, E fourteen, F fifteen, G sixteen, H seventeen, I eighteen, J nineteen, K twenty, and L twenty-one in decimal. Each digit’s position represents a power of 22, starting from $22^0$ at the rightmost digit and increasing to the left. For example, the base-22 number 3L7 equals $3 \times 22^2 + 21 \times 22^1 + 7 \times 22^0 = 1452 + 462 + 7 = 1921$ in decimal. Base-22 is primarily used in theoretical mathematics, number theory, and educational exercises to explore alternative numeral systems, positional notation, and arithmetic patterns. Understanding base-22 allows learners to perform arithmetic operations, convert numbers between bases, and analyze properties of non-decimal systems. Although rarely used in computing or daily life, studying the duovigesimal system improves logical reasoning, problem-solving skills, and comprehension of abstract number representations. It also provides a foundation for higher-level numeral systems, coding theory, and mathematical research, showing how numbers can be efficiently represented and manipulated in diverse bases.
