Why is 0 considered a natural number?

Zero does not have a positive or negative value. Zero is not positive or negative. Even though zero is not a positive number, it’s still considered a whole number. Zero’s status as a whole number and the fact that it is not a negative number makes it considered a natural number by some mathematicians.

How do you prove a number is natural?

The principle of induction provides a recipe for proving that every natural number has a certain property: to show that P holds of every natural number, show that it holds of 0, and show that whenever it holds of some number n, it holds of n+1. This form of proof is called a proof by induction.
