Hello,
New to the forum. Hope this is the right place for this question.
I'm reading How to Think Like a Mathematician by Kevin Houston.
I'm reading about sets, and he points out that {5} and 5 are not the same things. Can anyone explain what it means to have a set that contains only one element, and why you can't simply treat it as the one element?
Thanks much
