I’m trying to understand the difference between the following operators (not sure if that’s the right term in this case) and when each would be used. Hopefully the math geeks and semantic pedants here can be of help.

What is the difference between:

∈

∉

∋

∌

⊂

⊃

⊄

⊅

⊆

I know this has to do with sets, but I’m not entirely clear how to visualize the differences between “is a member of” and “Contains” or “Subset of” and Super set of".
