Number System


The base-13 number system, also called the tridecimal system, is a positional numeral system that uses thirteen symbols: 0, 1, 2, 3, 4, 5, 6, 7, 8, 9, A, B, and C, where A represents ten, B represents eleven, and C represents twelve in decimal. Each digit’s position represents a power of 13, starting from 13013^0 at the rightmost digit and increasing to the left. For example, the base-13 number 2B5 equals 2×132+11×131+5×130=338+143+5=4862 \times 13^2 + 11 \times 13^1 + 5 \times 13^0 = 338 + 143 + 5 = 486 in decimal. Base-13 is mainly used in theoretical mathematics and number theory to study alternative numeral systems, arithmetic patterns, and positional notation. Understanding base-13 allows learners to explore conversions between bases, analyze divisibility, and perform arithmetic in non-decimal systems. While it is not commonly used in everyday applications or computing, it provides a unique perspective on number representation and problem-solving. Studying the tridecimal system enhances comprehension of numeral systems beyond decimal, strengthens mathematical reasoning, and illustrates the flexibility of positional notation. It also serves as a foundation for exploring higher-level mathematics, coding theory, and abstract applications in theoretical number systems.

-35 Number System


The base-35 number system, also called the pentatrigesimal system, is a positional numeral system that uses thirty-five 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, T, U, V, W, X, and Y, 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, T twenty-nine, U thirty, V thirty-one, W thirty-two, X thirty-three, and Y thirty-four in decimal. Each digit’s position represents a power of 35, starting from 35035^0 at the rightmost digit and increasing to the left. For example, the base-35 number 3Y7 equals 3×352+34×351+7×350=3675+1190+7=48723 \times 35^2 + 34 \times 35^1 + 7 \times 35^0 = 3675 + 1190 + 7 = 4872 in decimal. Base-35 is mainly studied in theoretical mathematics, number theory, and educational exercises to explore alternative numeral systems, positional notation, and arithmetic patterns. Understanding base-35 allows learners to perform arithmetic operations, convert numbers between bases, and analyze properties of non-decimal systems. Although rarely used in daily life, studying the pentatrigesimal system enhances logical reasoning, problem-solving skills, and comprehension of abstract number representations.
