Let

be any integer. Then

In other words:
(1) If

is a multiple of 4, then

.
(2) If dividing

by 4 leaves a remainder of 1, then

, since

for some integer

, and from (1) we know that

(because, obviously,

is a multiple of 4).
(3) If instead you get a remainder of 2, then

. This follows from (1) as well.

.
(4) Finally, if you get a remainder of 3, then

.
