Number System

The base-6 number system, also known as the senary system, is a positional numeral system that uses six digits: 0, 1, 2, 3, 4, and 5. Each digit’s position represents a power of 6, starting from $6^0$ at the rightmost digit and increasing to the left. For example, the base-6 number 254 represents $2 \times 6^2 + 5 \times 6^1 + 4 \times 6^0 = 72 + 30 + 4 = 106$ in decimal. Base-6 is interesting in mathematics because 6 has multiple factors—2 and 3—making it highly divisible and useful for fraction representation. Historically, it has been proposed as an efficient numeral system for calculations, as many fractions that are repeating in decimal terminate in base-6. The senary system is sometimes studied in computer science and recreational mathematics for its unique properties and efficiency in representing numbers. It also serves as an educational tool for understanding how positional numeral systems work, exploring arithmetic in non-decimal bases, and analyzing number patterns. Though it is not widely used in modern technology, base-6 provides insights into alternative ways of counting, organizing data, and performing calculations. Studying it helps build a deeper understanding of number systems, divisibility, and the versatility of mathematical representations.

The base-15 number system, also called the pentadecimal system, is a positional numeral system that uses fifteen symbols: 0, 1, 2, 3, 4, 5, 6, 7, 8, 9, A, B, C, D, and E, where A represents ten, B eleven, C twelve, D thirteen, and E fourteen in decimal. Each digit’s position represents a power of 15, starting from $15^0$ at the rightmost digit and increasing to the left. For example, the base-15 number 2D4 equals $2 \times 15^2 + 13 \times 15^1 + 4 \times 15^0 = 450 + 195 + 4 = 649$ in decimal. Base-15 is primarily used in mathematical studies, number theory, and educational contexts to explore alternative numeral systems and positional notation. Understanding base-15 allows learners to perform arithmetic operations, convert between bases, and analyze patterns in numbers beyond the decimal system. Although not commonly used in computing or everyday applications, studying the pentadecimal system provides insights into the structure and versatility of numeral systems. It enhances mathematical reasoning, problem-solving skills, and comprehension of abstract number representations. Base-15 also serves as a foundation for exploring higher-level numeral systems, coding theory, and theoretical mathematics, allowing learners to understand how numbers can be efficiently represented and manipulated in various bases.
