Number Systems

Number systems are the foundation of mathematics and computer science. They are used to represent and manipulate numbers, and they play a vital role in everything from counting and arithmetic to calculus and cryptography. There are many different number systems, but the most common ones are the decimal system, the binary system, and the hexadecimal system.

History of Number Systems

The earliest number systems were developed by the ancient Egyptians and Babylonians. These systems were based on the number 10 and the number 60, respectively. The decimal system, which is based on the number 10, was developed in India around the 5th century AD. The binary system, which is based on the number 2, was developed by Gottfried Wilhelm Leibniz in the 17th century. The hexadecimal system, which is based on the number 16, was developed by IBM in the 1960s.

Types of Number Systems

There are many different number systems, but the most common ones are the decimal system, the binary system, and the hexadecimal system.

The decimal system is the most familiar number system to most people. It is based on the number 10, and each digit in a decimal number represents a power of 10. For example, the number 123 represents 1 × 10² + 2 × 10¹ + 3 × 10⁰ = 100 + 20 + 3 = 123.

The binary system is based on the number 2, and each digit in a binary number represents a power of 2. For example, the number 1011 represents 1 × 2³ + 0 × 2² + 1 × 2¹ + 1 × 2⁰ = 8 + 0 + 2 + 1 = 11.

The hexadecimal system is based on the number 16, and each digit in a hexadecimal number represents a power of 16. For example, the number A1F represents 10 × 16² + 1 × 16¹ + 15 × 16⁰ = 2560 + 16 + 15 = 2591.
