Number System

The base-2 number system, commonly called the binary system, is a positional numeral system that uses only two digits: 0 and 1. Each digit, known as a bit, represents a power of 2, with the rightmost position representing $2^0$, the next $2^1$, and so on. For example, the binary number 1101 equals $1 \times 2^3 + 1 \times 2^2 + 0 \times 2^1 + 1 \times 2^0 = 8 + 4 + 0 + 1 = 13$ in decimal. Binary is fundamental to computing and digital electronics because electronic devices operate in two states: on and off, represented by 1 and 0. This simplicity allows computers to store, process, and transmit data reliably. Binary numbers are used in memory storage, processor instructions, networking, logic circuits, and coding systems. Understanding base-2 is crucial for computer science, programming, and engineering because it explains how machines represent and manipulate information. Binary arithmetic, logic operations, and data encoding form the foundation for higher-level computations, making the base-2 system indispensable for modern technology, digital communications, and computing systems.

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.
