You only get to ask one question per post, and since your first question is nonsense, I'll do the second one. If you are having trouble with English, get someone to help you.
Let 
represent the 100s digit of the 3-digit number, 
represent the 10s digit, and 
represent the 1s digit. Then 
is a representation of the original number. The number obtained when the digits are reversed is then 
. And their difference is:
\ =\ 99x\ -\ 99z)
Which is evenly divisible by 99, hence the remainder is zero.
