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.

25 Number System

The base-25 number system, also called the pentavigesimal system, is a positional numeral system that uses twenty-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, and O, 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, and O twenty-four in decimal. Each digit’s position represents a power of 25, starting from $25^0$ at the rightmost digit and increasing to the left. For example, the base-25 number 3O7 equals $3 \times 25^2 + 24 \times 25^1 + 7 \times 25^0 = 1875 + 600 + 7 = 2482$ in decimal. Base-25 is primarily studied in mathematics, number theory, and educational contexts to explore alternative numeral systems, positional notation, and arithmetic patterns. Understanding base-25 allows learners to perform arithmetic operations, convert numbers between different bases, and analyze properties of non-decimal systems. Although rarely used in computing or daily life, studying the pentavigesimal system enhances problem-solving skills, logical reasoning, and comprehension of abstract number representations. It also provides a foundation for higher-level numeral systems, coding theory, and theoretical mathematics, helping learners understand efficient ways to represent and manipulate numbers in diverse bases.
