2018 is not a Palindrome, So...

A Palindrome is an integer that reads the same forwards as backwards. For example, 12321 is a Palindrome.

2018 is not a Palindrome. If I added an integer X to 2018, the resulting number is a Palindrome!

What is the smallest possible value of X?

The answer is -2018.

The smallest integer palindrome is 0. Notice that negative integers are not palindromic. Hence, the smallest possible value of integer X must be -2018.
