Natural numbers are a set of positive integers, starting from 1 and going up to infinity
. They are also referred to as counting numbers because they are used for counting objects and do not include zero, fractions, decimals, or negative numbers
. Some key points about natural numbers are:
- They are part of the number system and are used for counting purposes
- Natural numbers include only the positive integers, such as 1, 2, 3, 4, 5, 6, and so on
- They are a part of real numbers, excluding zero, fractions, decimals, and negative numbers
- Natural numbers are closed under addition and multiplication, meaning that the sum or product of two or more natural numbers will always be a natural number
- They do not include negative numbers or zero, as they are primarily used for counting objects
For example, the first ten natural numbers are 1, 2, 3, 4, 5, 6, 7, 8, 9, and 10
. Natural numbers are used in everyday life for counting objects, representing quantities, and telling time
