    The simplest way to put it is that 2 integers are congruent mod 4 if they have the same remainder when you divide by 4. So 1 and 9 would be congruent mod 4, while 1 and 7 wouldnt be.

    There is a little more to it than that, but this is the easiest way to put it.

    0's remainder when you divide by 4 is 0, so what other integers have a remainder of 0 when divided by 4?
