alot of teaser I found to have thousands of answers
any time a number is the exact reverse of another, their difference is exactly a multiple of 9, because since both the numbers use the same digits, they both get the same remainder after division by 9.
For two-digit numbers, the difference between the two digits multiplied by nine should be the distance from that number's reverse counterpart.
For example:
53
5-3=2 2x9=18
53 - 18 = 35
For two-digit numbers, the difference between the two digits multiplied by nine should be the distance from that number's reverse counterpart.
For example:
53
5-3=2 2x9=18
53 - 18 = 35
I just guessed with 36 on my first try.
