Cartesian Product/Examples/Product of Arbitrary Sets 2

Let $V = \set {v_1, v_2}$.
Let $W = \set {w_1, w_2, w_3}$.
 $\ds V \times W$ $=$ $\ds \set {\tuple {v_1, w_1}, \tuple {v_1, w_2}, \tuple {v_1, w_3}, \tuple {v_2, w_1}, \tuple {v_2, w_2}, \tuple {v_2, w_3} }$ $\ds V \times V$ $=$ $\ds \set {\tuple {v_1, v_1}, \tuple {v_1, v_2}, \tuple {v_2, v_1}, \tuple {v_2, v_2} }$
