Question 752387
<pre>
Such numbers as 101 AND 313 are called "palindromes".

Such numbers are of the form ABA

There are 10 digits but since we cannot choose 0
for the first digit in a 3-digit number, we can only 
choose one of the other 9 digits for the A.  For each
of those 9 ways to choose A, we can choose the B in
10 ways because 0 CAN be chosen for the middle digit B. 

So that's 9x10 wars or 90 ways
