A natural number is a positive whole number used for counting and
ordering. Typically, natural numbers start from 1 and go upwards:
1, 2, 3, 4, 5, and so on.
Key points about natural numbers:
- They do not include zero (in some definitions, zero is included, but traditionally natural numbers start at 1).
- They do not include fractions, decimals, or negative numbers.
- They are used for counting objects (like 3 apples) or ordering (like 1st, 2nd, 3rd).
Examples:
- 7 is a natural number.
- 0 is sometimes included but often considered a whole number instead.
- -3 or 2.5 are not natural numbers.
