What is the largest unit of counting in mathematics?
One, ten, one hundred, one thousand, ten thousand, one hundred thousand, one million, ten million, one billion, ten billion, one hundred billion, one trillion, ten trillion, one trillion, one trillion, one trillion, one trillion.

In the eyes of the ancients, those huge numbers, such as the stars in the sky and the sand in the sea, are endless and countless. Around the 3rd century BC, Archimedes, a great scientist, explained a method of writing huge numbers when calculating sand grains: he started with the largest number "Wan" in ancient Greek arithmetic at that time, introduced a new number "Wan" (1 billion) as the second-order unit, then "1 billion" as the third-order unit, and so on.

Finally, he concluded: "The number of sand grains that can be filled in the celestial sphere in the universe will not exceed10 million eighth-order units." Modern astronomers estimate that if the universe that can be observed by astronomical telescope is completely filled with sand, the amount of sand needed will exceed the power of 10/0/00 (1 followed by 100 zeros). This is of course much larger than the number of "Ganges sand" mentioned in Buddhist scriptures.

In ancient India and China, the notation of large numbers was closely related to Buddhism. The names of Indian large numbers and various ways of carrying them have been involved in the Buddhist scriptures translated in the Southern and Northern Dynasties. In the Yuan Dynasty, Zhu Shijie added six names of large numbers, such as Pole, Ganges Sand, Ajingdi, Nayuhe, Unbelievable, Infinite, Billion, Trillion, Beijing, Qi, Earth, Ditch, Flow, Righteousness and Load, to his arithmetic enlightenment.

In modern mathematics, the power of 100 is quite famous. 1940, the famous works Mathematics and Imagination by American mathematicians Edward Casner and James Newman first appeared and was named "Gugor". I don't know how many times bigger than googol is called googolplex, which is equal to 1 followed by googol zeros. This figure is impossible to write. But this is not the biggest. The largest finite number used in mathematical proof is the so-called Graham number, which was created by computer expert Donner in 1976.

This is the counting unit, depending on the counting method you use. There are three counting units * * *. One is Shangfa, which is a self-multiplying system: 1 billion, 1 billion is trillions, and trillions is Beijing. 10 4 = 10,000, 10 8 = 100 million,1kloc-0/6 = trillion, 10 32 = Beijing; The second is: China and France, which are both progressive systems, are all 10,000 advances: 1 trillion US dollars are in Beijing, and gullies (next to the earth) carry ┅ (10 trillion US dollars is trillion US dollars, and 10 trillion US dollars is Beijing ┅); 10 4 = ten thousand, 10 8 = one hundred million,10/2 = trillion,10/6 = Beijing; The third method is: the next method is decimal, and all of them are progressive.

The largest number in ancient Indian counting units.
