The Attempt at a Solution
(m-n)/=dk >>>>>(m-n)/d=k...equation 1
m mod d means m=dq1+r1 where q1 is the quotient and r1 is the answer for mod
n mod d means n=dq2+r2 where q2 is the quotient and r2 is the answer for mod
r1-r2= m-dq1-n+dq2 =(m-n)+d(q1-q2)
sub equation 1 into it,
(r1-r2)/d +q1-q2=k
how can i show that q1-q2 is equal to k so that i can conclude r1 and r2 is same. Any1?or any better solution?
