Define a relation Ton the set of real numbers as follows: Vx, y ≤R, x Ty ⇒xy < 0 The relation is not transitive since we can provide a counter example. The relation T is transitive. We can write a formal proof The relation is not transitive. take x=1 and y=-1 then xy=yx The relation is transitive. If we take x=-1, y=1, xy=-1 which is smaller than 0.
