Why are 10 Arabic numbers? Why not 11? We all know that Arabic numbers are in decimal order. How can we get this 10-digit number? I guess it's because people have 10 fingers? If so, it should be 1 to 10 plus a 0. Can anyone tell me? Posted on zuilang read (1551) Comments (6) EDIT favorites The comment counting method provides a representation of numbers. We use a 10-digit notation at most. It is said that each person has five fingers and five toes. In fact, this is just an interesting saying. You don't have to take it seriously. Since each hand has five fingers, why not use a 5-digit system? In history, there was almost no 5-in-number. The total number of fingers and toes is 20. Why is it not in hexadecimal notation? In addition to the 10-digit system, there are also 12-digit system, 16-digit system, 20-digit system, and 60-digit system. At present, the world has been moving towards integration. The adoption of "Metric" and "10-digit" is the trend of the times, but the United States and the United Kingdom are two stubborn, the British spoke of the pound and the shitter with 20-digit; the British and Americans use 12-in-size feet and inches, and 16-in-weight ounces and lbs... ..., The British and Americans seem to have deliberately avoided the 10 hexadecimal notation on the scale! This represents the arrogance, backwardness, or uniqueness of the United States? Without discussion, it is by no means "advanced" or "convenient ".

# What is the origin of the 10-digit system? Zuilang's blog accidentally?

# Re: Why are 10 Arabic numerals? Why not 11? Zetch 1, 2, 4, 5, 6, 7, 8, 9, 10
I don't know how the British wrote 11, but how does it represent it ??
At that time, the human memory may be very low. You cannot remember many symbols. Too many numbers are hard to remember, so there are 10. It's hard to say that it's too small to write.

# Because a person only has 10 fingers at hengai, because he only has 10 fingers, he is in 10 digits.
Later, because computers were not invented by the Arab people, and the United States and Britain, they always wanted to make special things, so the computers were made in hexadecimal notation (joke)

# Re: hengai zulang. If so, it should be 1 to 10 plus 0.

# Re: Why are 10 Arabic numerals? Why not 11? Dream books since 10 can already be expressed in 1 and 0, why do I need to add one more?
I admire those who have invented these 10 numbers. They are perfect.
