Proposition: Addition of Rational Cauchy Sequences Is Commutative

The addition of rational Cauchy sequences is commutative, i.e. for any rational Cauchy sequences \((x_n)_{n\in\mathbb N}\) and \((y_n)_{n\in\mathbb N}\) the following law is valid:

\[(x_n)_{n\in\mathbb N}+(y_n)_{n\in\mathbb N}=(y_n)_{n\in\mathbb N}+(x_n)_{n\in\mathbb N}.\]
