What is a natural number?
Definition What is a natural number? This is the number that occurs when counting in a natural way (in the process of listing or calculating).
To determine what is a natural number, there are two approaches:
- The numbers we use when numbering items.
for example: the first car, the second car, the third car.
- 2. The numbers that we use when we need to denote the number of objects.
for example: one kiwi, two kiwis.
All natural numbers make up the set, which is denoted by the sign N.
Now that we know what a natural number is, we can talk to other numbers. In addition to the natural there are also rational, integer, etc.
For example, rational is a number that looks like an irreducible ordinary fraction. This fraction has an integer in the numerator, and the denominator is a natural number.
