What is the difference between digits and numbers

A digit is a single symbol used to represent a numeral. There are ten digits: 0, 1, 2, 3, 4, 5, 6, 7, 8, and 9. In Latin, digit means fingers, and the word originates from the fact that ten digits of the hand correspond to the ten symbols of the common decimal numeral system.

We can use digits alone for example, 1 or in combination with other digits for example, 10, , etc. Therefore, we can say that a number or a numeral has several digits. For example, a phone number in the United States usually consists of eleven digits. The CVV number in the back of a credit or debit card typically contains three or four digits.

Similarly, a digital clock uses six digits to show time — two digits to show hours, two digits to show minutes and two digits to show seconds. But we generally use only 4 digits to write time using numbers as we only indicate hours and minutes; for example, A number is an arithmetical value we express by a word, symbol, or figure.

A number represents a particular quantity, and we use numbers in counting and making calculations. Many years before, ancient people needed to count objects. Therefore, numbers were introduced for counting and measuring purposes. During earlier days, they needed only whole numbers. Later on, rational numbers were introduced. In modern mathematics, we talk about different categories of numbers, such as real numbers, complex numbers, rational and irrational numbers etc.

Modern people needed to keep written records on quantity of things they owned, stored or sold. So, they needed a convenient and standardized system of symbols to represent numbers. Such a system of symbols is called a numeral system. Good question! The words digit and number can be confusing because they are closely related and often used in the same contexts, as in these examples:. A digit is any one of these symbols: 0, 1, 2, 3, 4, 5, 6, 7, 8, 9.

For example, the number 23 is written with two digits, 2 and 3. A number is an amount of something. It can be written with one or more — or many — digits. Numbers can also be written with words. A number can also be a series of digits that is used to identify something, such as a phone number, apartment number, or social security number.
