Famous method

There are two ways to count. It is a way of calling in words and a way of expressing in numbers. They are called the Mungso method and the Radix method, respectively. You can easily read large or small numbers using the naming method. This is because the unit is given a name. Here, the units are one, ten, one, ten, ten, and so on. For example, the 3230000 units represented by a number symbol can be read as 32.3 million.

Ten thousand units become billions after ten thousand, one lakh, one million, ten thousand, one lakh, one lakh, one lakh, ten, one hundred billion and so on. Our ancestors named large numbers of Chinese characters under the influence of China, and there are famous numbers in the mathematical book The Arithmetic New Book, written in 1900 by Lee Sang-seol. Billion (億), Joe (兆), Jeong (京), He (垓), Ja (J), Yang (穰), Gu (溝), Liver (澗), Jeong (正), Jae (載), Guyk (極), Hungasa (恒河沙), Ahsiungi (阿僧祇), Nayuta (那 他), Nigu (Ta (不可思議), Mu-Riangsu ()

The name of each number has a meaning. Of these, navigator means ‘Ganga’, the Chinese symbol for the river Ganga in India, and ‘Sa’ means sand. In other words, the number of sergeants is as large as the grains of sand in the Ganges. All units larger than the Hang Sergeant are words found in Buddhist scriptures. Xiongji Ah means ‘for a long time’, and surprisingly ‘something that can not be thought of with common sense’. Listening to the meaning, can you understand how big it is? A random number is 69 digits with 68 zeros.

The way we read numbers is different in the West. A new unit is used every ten thousand times in Korea, China, and Japan, but a new unit is used every thousand times in the United States and other Western countries. Thousands upon thousands, millions of people, 1 billion are called billions.

Here’s an interesting story about the largest numbers in the world. In 1938, American mathematician Edward Cassner asked his nine – year – old son – in – law, Milton, what he called the largest number in the world. “Gogol,” Milton replied. When Cassner asked Milton how big he was, Milton said, “It’s a number I can no longer use because my hand hurts when I write a number.” Based on Google, Kasner created another new unit, Googleplex. Cosnor did not initially define a Googleflex number that is tired of writing 0 after 1. Later, it was redefined as a 1-goal number after 1 0.

Google, the world’s largest Internet search service, was originally called Google. It was the name that expressed the desire to search all the innumerable data available on the Internet and Google. However, the person who went to register the company name is said to have become Google because the spelling in Google was misspelled.
