discrete math: is there a difference between $\subseteq$ to $\supseteq$

Question

I have a question which asks if $X \supseteq I$. Is it just the same as $I \subseteq X$?

Because I never saw it the other way around or learned about it, I'm confused.

Answer 1

Taking from mookid, so we have an answer, yes.

Answer 2

Wikipedia article about subset says:

If $A$ and $B$ are sets and every element of $A$ is also an element of $B$, then:

• $A$ is a subset of (or is included in) $B$, denoted by $A \subseteq B$,

or equivalently

• $B$ is a superset of (or includes) $A$, denoted by $B \supseteq A$.
