# Question concerning the influence of interchanging factors of an infinite product on the value of the product

I am searching for a proof of the following fact:

If an infinite product $\prod\limits_{n=1}^{\infty} (1+a_n)$ of complex numbers is absolutely convergent, then its factors can be reordered without affecting the value of the product.

Thanks for the help!

• I think that it is worth mentioning that this is closely related to your previous question. – Martin Sleziak Mar 8 '15 at 7:36
