Order

The definition of *set* states that a "set is an **unordered** collection of elements. What does this mean about sets C and D, below?

C={10,27,4}D={4,10,27}

Sets C and D are equal because there elements are the same. The only difference is the order, which doesn't matter.

So 84 is correct.
