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 decimal number system, also known as base-10, is the standard numeral system used in everyday life. It uses ten digits: 0, 1, 2, 3, 4, 5, 6, 7, 8, and 9. Each digit’s position in a number represents a power of 10, starting with $10^0$ at the rightmost position and increasing to the left. For example, the decimal number 482 represents $4 \times 10^2 + 8 \times 10^1 + 2 \times 10^0 = 400 + 80 + 2$. The decimal system is the most familiar because humans naturally count using ten fingers, which likely influenced its widespread adoption. It is used in daily activities such as measuring, shopping, banking, and science. In computing, decimal is often contrasted with binary, octal, or hexadecimal systems, which are more suitable for digital devices. Understanding decimal is essential for arithmetic operations, financial calculations, and data representation. It also serves as a foundation for learning other positional numeral systems, as conversions from binary, octal, or hexadecimal often rely on an intermediate decimal representation. The decimal system’s simplicity and universality make it a fundamental tool in mathematics, education, and daily life.
