Do you claim that the sets {x,y} and { {}, {x}, {y}, {x, y} } are equal?

Joe G:
Let x = $10 and y = $20
The set {x,y} contains $30
the power set { {}, {x}, {y}, {x, y} } also contains $30.
$30 = $30

I didn't see this before my last post. The two sets are definitely not the same, however.

The CONTENTS are the SAME- they are EQUAL.
$30 = $30 so {x,y} has to equal { {}, {x}, {y}, {x, y} }
What part of that don't you understand?
