What is a palindrome in math? In math, a palindrome, also called palindromic number, is a number that reads the same from right to left and from left to right. For example, 767, 9, 321.123, and 8008 are examples of palindromes.
Notice that single-digit numbers and decimals can be palindromes.
If you read 9 from left to right, you get 9 and you read 9 from right to left you still get 9.
A negative number cannot be a palindrome. For example, -61716 is not a palindrome. If you read -61716 from left to right, the negative sign is on the left. However, if you try to read the number from right to left, you will get 61716-
Since we never put a negative sign on the right of a number, -61716 is not a palindrome.
