# Number and Digit

**Number and Digit what is difference?** First of all, you need to know that the symbols that
are used to indicate the numbers were invented in India 1,500 years ago. The Europeans
learned about these symbols from the Arabs, because the Arabs began to use them before
anyone else. And the rest of the peoples learned about them from the Arabs.

What does the word digit mean? This word is of Arabic origin and means zero or empty
space. There are only ten of them. They are designed to represent a number. Here's a list:

## 0, 1, 2, 3, 4, 5, 6, 7, 8, 9.

True, there are only 10 of them. But zero is not used for counting. Therefore, the counting
begins like this: one, two, three ............ and e.t. What is the difference between a number
and a digit?

Let's now see how a number differs from a digit. If digits did not exist, numbers would not
exist. The first of them is 10. To write ten you need two digits 1 and 0. This is exactly why
digits were needed, they denote numbers. Numbers differ from digits in that they have no
end. They start at ten and do not end. For example:

## 10, 11, 12, 13, 14, 15, 16, 17, 18, 19, 20, 21, 22, 23, 24, 25 ........ 102 ..

The numbers listed here are called natural numbers. In the series of natural numbers, each
previous number is greater by 1. Therefore, they cannot be counted.

In addition to Arabic numbers, we also know Roman numbers. Roman is also used for,
designation of quantity. And these numbers can also denote an unlimited number. But
Arabic numbers are much more practical, so Roman numbers were replaced with Arabic
ones. Roman:

## I, V, X, L, C, D, M

There were times when people didn't have counting systems. But after centuries, people
began to invent them. For example, many ancient peoples had alphabets, they used the
letters of the alphabet as numbers. But then, when empires conquered countries in those
countries, they began to use those systems and symbols that empires used. This is why
almost the entire world has used Roman numbers. But in the Middle Ages, the Pope saw the
Arabic numeral system and realized that it was much more practical than the Roman
system, and began to promote this system. Besides this, the Maya had a system of numbers,
it is also similar to these systems. By the way, you can see it in the left menu.
