Number System

The base-17 number system, also known as the heptadecimal system, is a positional numeral system that uses seventeen symbols: 0, 1, 2, 3, 4, 5, 6, 7, 8, 9, A, B, C, D, E, F, and G, where A represents ten, B eleven, C twelve, D thirteen, E fourteen, F fifteen, and G sixteen in decimal. Each digit’s position represents a power of 17, starting from $17^0$ at the rightmost digit and increasing to the left. For example, the base-17 number 3F6 equals $3 \times 17^2 + 15 \times 17^1 + 6 \times 17^0 = 867 + 255 + 6 = 1128$ in decimal. Base-17 is primarily used in theoretical mathematics, number theory, and educational contexts to explore alternative numeral systems and positional notation. Understanding base-17 allows learners to perform arithmetic operations, convert between numeral systems, and analyze patterns in numbers beyond decimal. Although it is rarely used in computing or daily life, studying the heptadecimal system enhances mathematical reasoning, problem-solving skills, and comprehension of abstract number representations. It also provides a foundation for exploring higher-level numeral systems, coding theory, and theoretical applications, helping learners understand how numbers can be efficiently represented and manipulated in diverse bases.

31 Number System

The base-31 number system, also called the untrigesimal system, is a positional numeral system that uses thirty-one 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, Q, R, S, and T, 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, Q twenty-six, R twenty-seven, S twenty-eight, and T twenty-nine in decimal. Each digit’s position represents a power of 31, starting from $31^0$ at the rightmost digit and increasing to the left. For example, the base-31 number 3T7 equals $3 \times 31^2 + 29 \times 31^1 + 7 \times 31^0 = 2883 + 899 + 7 = 3789$ in decimal. Base-31 is primarily used in theoretical mathematics, number theory, and educational exercises to explore alternative numeral systems, positional notation, and arithmetic patterns. Understanding base-31 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 untrigesimal 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.
