Given: A= {1,2,3,4,6}
R = {(x,y)|x divides y}
a divides b if there exists an integer ¢ such that b= ac Notation: a|b
We then add the ordered pair (x,y) to R whenever x divides y.
Remember that an integer also divides itself.
R = {(1,1), (1,2), (1,3), (1, 4), (1,6), (2,2), (2,4), (2,6), (3, 3), (3,6), (4,4), (6,6)}
