P Adic Number

+A p-adic number offers an alternative system for counting, where numbers are considered "close" if their difference is divisible by a high power of a fixed [Prime Number](/wiki/prime_number) *p*. Unlike [Real Numbers](/wiki/real_numbers) which extend to infinite decimals, p-adic numbers extend infinitely to the left in base *p*. This unique metric reveals fascinating structures in number theory.
