The smallest palindrome is 1 or I
10+1=11 (which is a palindrome)
I think so.
A palindrome day reads the same backwards and forwards, like 2/1/12
A palindrome is a word, phrase, or sequence that can be read the same forward and backward. So technically, 1 can be the smallest.

One. If you mean "digits", the number can have any amount of digits; the only requirement to be called a "palindrome" is that if you read it backwards, you get the same sequence of digits. Thus, any of the following is a palindrome: 1 (any 1-digit number is a palindrome), 55, 121, 2002, 12321, 600006, 8105018, ... As you can see, you can make them arbitrarily large.
Subtract 1
19 is a two step palindrome because it takes two steps or two addition sums to make it a palindrome. Step 1 is 19 plus 91 equals 110. Step 2 110 plus 011 is equal to 121 and 121 is a palindrome.
"The proof of it will turn to redder drops." The palindrome is, of course, "redder".
