Number System

The base-11 number system, also called the undecimal system, is a positional numeral system that uses eleven distinct symbols: 0, 1, 2, 3, 4, 5, 6, 7, 8, 9, and A, where A represents ten in decimal. Each digit’s position represents a power of 11, starting from $11^0$ at the rightmost digit and increasing to the left. For example, the base-11 number 2A3 equals $2 \times 11^2 + 10 \times 11^1 + 3 \times 11^0 = 242 + 110 + 3 = 355$ in decimal. Base-11 is mainly used in mathematical studies, number theory, and educational contexts to explore alternative numeral systems. It provides insights into arithmetic operations, positional notation, and conversion between bases. Understanding base-11 helps students and researchers recognize patterns in numbers, learn divisibility rules, and analyze properties of non-decimal systems. While it is not commonly used in computing or daily life, it serves as a useful tool for abstract mathematics and theoretical applications. Studying base-11 strengthens comprehension of how numbers can be represented in various bases, enhances problem-solving skills, and lays the groundwork for exploring higher-level numeral systems such as base-12, base-16, and beyond.

Number System

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.
