how do you know (m + dk) mod d = m mod d + dk mod d?
is that a rule that works for all integers?
Yes, it does. The remainder when a + b is divided by d is congruent to the sum of the remainder of a when divided by d and the remainder of b when divided by d.
sorry to hop on your thread with a question, but did you ever figure out how to prove that? I have the same exact problem and cannot figure it out at all, driving me insane and its due in about 6 hours
