Number System

The base-4 number system, also known as the quaternary system, is a positional numeral system that uses four distinct digits: 0, 1, 2, and 3. Each digit’s position represents a power of 4, starting from $4^0$ at the rightmost digit and increasing to the left. This system is similar to binary (base-2) and decimal (base-10) systems but is specifically useful in applications where data can naturally be divided into four states, such as in certain digital circuits or computing systems. For example, the base-4 number 213 represents $2 \times 4^2 + 1 \times 4^1 + 3 \times 4^0 = 32 + 4 + 3 = 39$ in decimal. Base-4 is also efficient for representing binary data because every base-4 digit corresponds to exactly two binary digits, simplifying the conversion between binary and quaternary systems. Quaternary systems can be used in computer science, coding theory, and mathematics to reduce complexity in specific algorithms and storage systems. Learning and understanding base-4 helps in exploring alternative numbering systems, enhances computational thinking, and provides insights into how different bases represent quantities and perform arithmetic operations.

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.
