Cool math Order sets
No, not the order of the elements. In sets it does not matter what order the elements are in.
Example: {1,2,3,4) is the same set as {3,1,4,2}
When we say "order" in sets we mean the size of the set.
Just as there are finite and infinite sets, each has finite and infinite order.
For finite sets, we represent the order by a number, the number of elements.
Example, {10, 20, 30, 40} has an order of 4.
For infinite sets, all we can say is that the order is infinite. Oddly
enough, we can say with sets that some infinities are larger than
others, but this is a more advanced topic in sets.
