Verify with numbers 72 and 36 that the sum of a number and the number obtained by reversing it's digit is always divisible by 11

Dear Student,
If the number is 72,
Then, after reversing the digits it will be 27
Then their sum will be 27+72=99
Which is divisible by 11
If the number is 36,
Then, after reversing the digits it will be 63
Then their sum will be 36+63=99
Which is divisible by 11
Hence, with both the numbers it is justified!
Regards
