The Peano axioms, established by Giuseppe Peano, are fundamental in defining natural numbers and their arithmetic. These axioms introduce a base number and a successor function to generate the sequence of natural numbers. They ensure a distinct successor for each number and support the principle of mathematical induction, which is crucial for proofs and recursive functions in various mathematical disciplines.

The third axiom solidifies 0's position as the starting element by declaring that it is not the successor of any natural number
The fourth axiom guarantees the distinctness of each number in the sequence by asserting that no two different natural numbers can have the same successor
The fifth axiom, known as the Principle of Mathematical Induction, is a powerful tool for proving mathematical theorems by stating that a property that holds for 0 and its successor must be true for all natural numbers
