## Who Invented Number

The concept of numbers is one of the most fundamental concepts known to mankind. The invention of numbers traces back to ancient times, where it was used in various forms across different cultures.

### The Early History of Numbers

Humans have been using numbers for thousands of years, and evidence of number systems dates back to ancient civilizations. The earliest known counting device is the Ishango bone, a tool made of baboon fibula, discovered in Congo, Africa, dating back over 20,000 years ago.

Ancient Sumerians used a sexagesimal system of counting, using a base of 60, which influenced modern-day measurement systems, time and angles. The Babylonians also used a sexagesimal system and were the first to introduce a place-value system using a base of 60.

### Number Notation in Different Cultures

The way numbers were written and represented varied across cultures, from the tally marks of prehistoric times to the Roman numerals of the ancient Romans. The Egyptians used hieroglyphs to represent numbers while the Greeks used the letters of their alphabet to represent numbers.

The Romans developed a system for writing numbers using seven letters of the Latin alphabet, which is still used widely today. The Mayans developed a base-20 numbering system, and their numerical symbols included dots, lines, and an abstract symbol for zero.

### The Emergence of Modern Numerals

The numbers we use today, also known as Arabic numerals, were developed in India during the Gupta period and later introduced to Europe by Arab scholars. These numerals, consisting of ten digits (0-9), with a place-value system, have revolutionized mathematics and made complex calculations much more accessible.

Arabic numerals replaced the Roman numeral system in Europe during the 11th and 12th centuries, and they have now spread worldwide and are the most widely used number system.

In Conclusion, the concept of numbers has an extensive and fascinating history that dates back to ancient times. Numerous civilizations around the world have developed different forms of numbers and numerical systems. Nowadays, we use the Arabic numeral system, which was invented in India and introduced to Europe by Arab scholars, and it has become the de facto standard worldwide.

Numbers have been a critical part of human life for thousands of years and are used in several everyday activities. From counting money to keeping track of time, numbers are an essential element of our daily routines. The study of numbers, known as mathematics, has been an ongoing endeavor since ancient times. Many great minds have contributed to the development of numbers and mathematics throughout history. Here are three notable contributors:

### Pythagoras and Mathematics

Pythagoras was a renowned Greek philosopher and mathematician who lived in the 6th century BCE. He is well-known for his work on the Pythagorean theorem, which explains the relationship between the sides of a right-angled triangle. However, Pythagoras made several other mathematical discoveries, including the relationship between numbers and geometry, which played a considerable role in the development of mathematics.

Pythagoras believed that numbers had mystical properties and that everything in the universe could be explained by numbers. He developed the concept of numerical ratios, and his work on harmonics and music is still studied to this day.

### Al-Khwarizmi and Algebra

Al-Khwarizmi was a Persian mathematician who lived in Baghdad during the 9th century CE. He is regarded as the father of algebra and made significant contributions to the development of this field of mathematics. Al-Khwarizmi wrote the book "Al-Jabr wa-al-Muqabala," which laid the foundation for algebraic equations and explained how to solve them systematically.

Al-Khwarizmi's work also helped spread the use of decimal numerals and Arabic numerals across the globe. The word "algorithm" is derived from his name, and his contributions to mathematics have had a lasting impact on the world.

### Leonardo Fibonacci and the Fibonacci Sequence

Leonardo Fibonacci was an Italian mathematician who lived in the 13th century CE. He is known for introducing the Hindu-Arabic number system to the Western world, which is now widely used for mathematical calculations. Fibonacci's most significant contribution to mathematics is the discovery of the Fibonacci sequence, a mathematical sequence that starts with 0 and 1 and is derived by adding the two preceding numbers.

The Fibonacci sequence appears in several places in nature, including the spiral of seashells and the arrangement of leaves on a stem. It is still studied today as a fundamental part of number theory and has several applications in the field of computer science.

In conclusion, the development of numbers and mathematics has been an ongoing endeavor for thousands of years. Pythagoras, Al-Khwarizmi, and Fibonacci are three notable contributors who played a significant role in shaping the field of mathematics. Their work has had a lasting impact on the world and will continue to be studied by future generations of mathematicians.

Keys may have been invented in ancient Rome, but their modern form did not appear until the Middle Ages.
