Frequently Asked Questions
?What is a palindrome number?
A palindrome number reads the same forwards and backwards, like 121, 1331, or 12321.
?Is a single digit a palindrome?
Yes. Every single-digit number (0–9) is a palindrome by definition.
?Are negative numbers palindromes?
This tool ignores the negative sign and checks the absolute value. So -121 checks 121, which is a palindrome.
?What about numbers with leading zeros?
Numbers don't have leading zeros, so 010 is treated as 10, which is not a palindrome.

Examples include 1234321, 99999999, and 1000000001.
