Cardinality of Cartesian Product of Finite Sets/Corollary/Proof 1

Corollary to Cardinality of Cartesian Product
Let $S \times T$ be the cartesian product of two sets $S$ and $T$ which are both finite.

Then:
 * $\left|{S \times T}\right| = \left|{T \times S}\right|$

where $\left|{S \times T}\right|$ denotes the cardinality of $S \times T$.
