There are the same number: any twelve digit palindrome is just an eleven digit palindrome with its central digit repeated. In general, if we are considering numbers of n digits: For even values of n, the number of palindromes is 9 x 10n/2 - 1 For odd values of n, the number of palindromes is 9 x 10(n-1)/2
2 digit number
Highest 2-digit number = 99 Highest 1-digit number = 9 Highest possible sum from 2, 2-digit numbers = 198 Highest possible sum from 2, 1-digit numbers = 18
The only number that fits those conditions is... 55
1 to 1000. Pilandromic 108
It is 77.It is 77.It is 77.It is 77.
The only 2-didgit palindromic prime is 11.
A palindromic number is the same forwards as backwards. In the case of a two-digit number, that means the two digits are the same: 11, 22, 33, 44, 55, 66, 77, 88, and 99. The only one that is prime is 11, since the others are all multiples of 11.

I suppose you meant palindrome. Palindromic number in maths means number which stays same if we reverse it. e.g. 11, 151, 6886 are palindromic, but 1211, 100 or 15 aren't. 1, 2, 3, 4, 5, 6, 7, 8 and 9 are considered palindromic too.
The leading digit in a number is the digit to the most left. EXAMPLES: 1.09 the leading digit is 1. 298 leading digit 2.
