When to use which one
You might be thinking 那 and 这 have different meanings. “How can they be used the same way?” Well, there are some differences. "这么" is used when the thing you are talking about is close by, when you would say "this" or "这个." On the other hand, if the object is far away, you would use "那么." Furthermore, this distance doesn't have to be physical, it can also refer to time, so you would use "那么" with things like "yesterday" or "tomorrow."
