Why was the counting unit invented in this way?
But even with this unit, our life is still inconvenient. If one day we kill a lot of prey, there will be many symbols to draw. Even if we draw it, what is the point? Just a bunch of symbols piled together like prey.
As a result, people have developed from a number to dozens, and it is also stipulated that 1 a "ten" equals1a "one"; Is it enough to have a counting unit of "ten"? With the enhancement of human ability and the development of science and technology, the counting unit of "ten" can no longer meet people's needs. Therefore, human beings invented larger counting units "hundred", "thousand" and "ten thousand". As before, the relationship between these counting units is decimal. The names of "Ge", "Ten", "Hundred", "Thousand" and "Wan" are different, so we call this naming method "individual naming".
What if you want to invent a bigger counting unit? Continue to use the method of "separate naming" as before? For example: one, ten, one hundred, one thousand, ten thousand, flowers, birds, fish, insects ... this is certainly possible, and we can continue to invent endlessly, but when the number of digits increases, it is not easy to remember, and there is no relationship between different digits. One more question. Everyone has different ideas. You want to name it this way, and he wants to name it that way. Without a unified answer, it is difficult for us to communicate.
In order to better invent larger units, the renaming method was changed to compound naming, that is, naming after the previous counting units. So the next one is very simple. After 10 thousand, it's 100 thousand, 1 million, 10 million Then you will blurt out that the next one is 10 million. What's next? You might say100000, millions, tens of millions, all the way to100000. ...
Although this can also create countless units, and there are certain connections between different units, it is very inconvenient to use. If you say I have ten thousand days and nights in Qian Qian, huh? It will take a long time for the other party to know the result of the analysis, because how big is Qian Qian? Therefore, we can choose another way-renaming. Ten million years later, we created billions, then billions, billions, billions. ...
You may ask why there is no "trillion"? My understanding is that in order to facilitate reading, we grade every four digits, and renaming it after 1000 billion is more in line with our grading habit, or you have other explanations, please communicate with me.
According to the previous chapter, after 1000 billion bits, it will be renamed, I know it is megabit, and then continue to use compound naming, that is, ten megabytes, hundreds of megabytes, gigabytes, ... and then rename it again. Will there be "honesty" in this world? If there is, then there are ten faiths, one hundred faiths, one thousand faiths, one thousand faiths ... It's really fun!
