FAQs on Fun Video: History of Numerical System Video Lecture - Advance Learner Course: Mathematics (Maths) Class 5

1. What is the history of the numerical system?
Ans. The history of the numerical system dates back to ancient civilizations such as the Babylonians, Egyptians, and Romans. These civilizations developed their own unique ways of representing numbers, which eventually evolved into the numerical system we use today.
2. How did the Babylonians represent numbers in their numerical system?
Ans. The Babylonians used a base-60 system known as sexagesimal. They used a combination of symbols to represent different values, with each symbol indicating a specific power of 60. This system allowed them to represent large numbers and perform complex calculations.
3. What were the symbols used by the Egyptians in their numerical system?
Ans. The Egyptians used a hieroglyphic system to represent numbers. They had different symbols for the numbers 1 to 9, and then used multiples of these symbols to represent larger numbers. For example, the symbol for 1 was a vertical line, and they would repeat this symbol to represent multiples of 10, 100, and so on.
4. How did the Roman numerical system work?
Ans. The Roman numerical system used a combination of letters to represent different values. For example, I represented 1, V represented 5, X represented 10, and so on. The system also had rules for subtracting and adding values to derive the desired number. However, this system was not as efficient as the decimal system we use today.
5. When and how did the decimal numerical system come into existence?
Ans. The decimal numerical system, based on the Hindu-Arabic numeral system, originated in India around the 6th century. It was later adopted and spread by Arab mathematicians during the Islamic Golden Age. This system introduced the use of positional notation, where the value of a digit depends on its position within a number, making it highly efficient for mathematical calculations.
