# Number and Digit

A number and a digit are used to write a quantity. With their help, you can write any number. People have been using numbers for a long time because they are an
integral part of our lives. Throughout history, a number of character sets have been created that people use for numbering, mathematical operations such as: addition, subtraction, division, multiplication, etc.

Human efforts have finally perfected the character set. It also contributed to the technological progress that we have today.

## The difference between a digit and a number

What is the difference between a digit and a number. Although they are both used for the same purpose, there is still a difference, and it is necessary to know it.
To fully understand this issue, you first need to know:

- What is a digit?
- What is a number?

Learn more about each of them and gain knowledge that will help you have a clear understanding of this simple but important issue. Below is a brief and understandable information about each of them. And at the bottom of the page there is a table of differences, which you can print or download.

## Digit

**A digit** is a special character that is used to represent a quantity. And each of them indicates a specific amount. The total number of digits is ten:
**0, 1, 2, 3, 4, 5, 6, 7, 8, 9.** The numbers are used both for numbering and for compiling numbers. The modern system belongs to the decimal counting system.

## Number

**A number** is a combination of at least two digits (a symbol). The smallest number is 10. To write it, you need to apply two digits 1 and 0 to get 10. Using numbers, you can write any amount. The number can contain any number of digits. For example, there are 7 digits in a million: 1 0 0 0 0 0 0. The modern decimal counting system has simplified the compilation of large numbers and the performance of mathematical operations on them.
