The number system we commonly used, known as the decimal system, has 10 digits (0 to 9). It is possible to use other number systems, with a different number of digits. Any numbering system based on the same principle (the principle of place-value) must use 2 or more digits.

A number is made up from digits in the numeral system. We often use the decimal system in which we use 10 digits, In writing the any number, many digits are used, even repitation of digits. when we write any number using the digits, the last digit ( from right side ) in that number is called unit digit. for example in the number 9814868980, here 0 is called unit digit.
