It's really very simple actually. One of the easiest math I think.
X={1,2,3,4,5}
means X is a set of 5 elements, the elements being - 1,2,3,4 and 5.
A={1,2}
means A is a set of 2 elements, the elements being - 1 and 2.
This also means that A is a subset of X, i.e, all the element in A exists in X.
B={4,3}
B is also a subset of X.
But even though B and A are subsets of X, they are not equal to X.
For a set to be equal to X it has to be a subset of X and X has to be a subset of that set.
This basically shows that even though a set may consists of all the elements it does not equal to any other subset of it(exception when the subset is X itself).
In simple terms, even though design comprises everything, design is not everything. This was a response to Rhythm because he thought since I was saying design comprises everything design is indistinguishable from something like apple.
