Author: mepinoargote Subject: a question about remainders Posted: Fri Sep 03, 2010 5:31 pm (GMT -7) When a possitive integer is divided by 7, the only possible remainders are 0,1,2,3,4,5 and 6. Also, each of these remainders will occur exactly once when the terms in a sequence of 7 consecutive integers are divided by 7. This is an explanation i got from OG about remainders, Can i generalize this rule when dividing a possitive integer by any n possitive integer
