To be a 3 digit palindromic number, it must be of the form aba.
I assume that a 3 digit number must be at least 100 (so that 020 for example does not count as a 3 digit number):
Thus there are 9 x 10 = 90 three digit palindromic numbers.
Twenty.
Oh, what a happy little question! There are 90 three-digit palindromic numbers in total. You see, they start at 101 and end at 999, with each one bringing its own unique charm and symmetry to the canvas of mathematics. Just imagine the joy of exploring all these lovely palindromic numbers!

a 8-digits palindromic number is a number consisting of a 4-digits number written and then written backward, i.e. 1234 4321 so there are as many palindromic 8-digits numbers as 4-digits numbers so from 1000 to 9999, so there are 8999 palindromic 8 digits number (I assumed that 00011000 is not to be considered as a valid 8 digit number)
There are 90 palindromic numbers between 100 and 1000
There are 900 three-digit numbers, ranging from 100 to 999.

There are not just 13 non-palindromic numbers. Most numbers are non-palindromic.

There are 900000 of them.
