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.

Number System

The hexadecimal number system, also known as base-16, is a positional numeral system that uses sixteen distinct symbols: 0, 1, 2, 3, 4, 5, 6, 7, 8, 9, A, B, C, D, E, and F. The letters A to F represent decimal values 10 to 15, respectively. Each position in a hexadecimal number represents a power of 16, starting from $16^0$ at the rightmost digit. For example, the hexadecimal number 2F3 equals $2 \times 16^2 + 15 \times 16^1 + 3 \times 16^0 = 512 + 240 + 3 = 755$ in decimal. Hexadecimal is widely used in computing and digital electronics because it provides a compact way to represent binary numbers, where each hex digit corresponds exactly to four binary digits. This makes conversion between binary and hexadecimal simple and efficient. Hexadecimal is commonly used in memory addressing, color coding in web design, and programming to simplify representation of large binary values. Understanding hexadecimal is essential for computer scientists, programmers, and engineers, as it bridges the gap between human-readable numbers and machine-level binary code, facilitating efficient computation, debugging, and data interpretation.
