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.

The base-12 number system, also known as the duodecimal system, is a positional numeral system that uses twelve symbols: 0, 1, 2, 3, 4, 5, 6, 7, 8, 9, A, and B, where A represents ten and B represents eleven in decimal. Each digit’s position represents a power of 12, starting from $12^0$ at the rightmost digit and increasing to the left. For example, the base-12 number 3B4 equals $3 \times 12^2 + 11 \times 12^1 + 4 \times 12^0 = 432 + 132 + 4 = 568$ in decimal. Base-12 has historically been used in counting systems, timekeeping, and measurements, such as a dozen or hours on a clock. It is valued for its divisibility, as 12 can be evenly divided by 2, 3, 4, and 6, making fraction representation simpler than in decimal. The duodecimal system is also studied in mathematics for its interesting arithmetic properties, positional notation, and numeral patterns. Understanding base-12 provides insights into alternative counting systems, number theory, and conversions between numeral bases. It enhances problem-solving, logical thinking, and understanding of how different bases represent quantities, making it a useful concept in both historical and theoretical mathematics.
