Digits in our Daily Use
There are ten digits in our daily use: 0, 1, 2, 3, 4, 5, 6, 7, 8, 9. Each digit has a unique value and can be used to represent different quantities. For example, the number 9 can represent the quantity nine, ninety, or nine hundred.
In our modern world, we use digits in many ways every day. We use digits to communicate with others, to make financial transactions, and to keep track of our personal belongings.
The use of digits for communication is evident in the way we use telephone numbers to contact people. A telephone number is composed of ten digits, which are separated into three parts. The first three digits are the area code, the next three digits are the exchange, and the last four digits are the telephone number. This system of numbering was developed in the 1940s, and it has been used ever since.
