If A _ {1, 2, 3, 4, 5, 6, 7}, define _ on A by (x, y) ∈ _ if x − y is a multiple of 3.

OpenStudy (zzr0ck3r):

define _ is a set in R^2?

OpenStudy (sweetshiva9963):

yea. I just not sure the rest

OpenStudy (zzr0ck3r):

it does not make sense to say define a set on a set, from what I know... And if _ is an operation then the other part of the question does not make sense... IM confused.
