WebAug 1, 2014 · Its not a good idea to use subtraction, for by default that relation is not symmetric. However you are correct. But I would suggest the following : $(a,b)R(c,d) \iff a+d =b+c \equiv (a,b)R(a,b) \iff a+b =a+b$ therefore R is trivially reflexive. $$(c,d)R(a,b) \iff c+b=d+a $$*and so a+d=b+c, which means (a,b)R(c,d)*.
