1. Wait patiently for a helper to come along.
2. Once someone helps you, say thank you and close the thread with:

+close

3. Feel free to nominate the person for helper of the week in #helper-nominations
4. Do not ping the mods, unless someone is breaking the rules.
5. If you're happy with the help you got here, and the server overall, you can contribute financially as well:

Yes.
Basically, here you need to see the difference between elements and subsets.
So, for example, {1} is both an element and a subset of {1, {1}}, but 1 is only an element of that set.

Just a quick question

It would also be wrong to use the ⊆ in relations between mere elements and sets, right? Like 2 ⊆ A. I know this is stupidly dumb, I just want to confirm that it's all right

it is not the right thing to do, use "in"

$\in$
