Pointwise Addition on Complex-Valued Functions is Commutative

Definition
Let $S$ be a set. Let $f, g: S \to \C$ be complex-valued functions.

Let $f + g: S \to \C$ denote the pointwise sum of $f$ and $g$.

Then:
 * $f + g = g + f$

That is, pointwise addition of complex-valued functions is commutative.
