7
To make it a bit more intuitive, think of it like this: If you have a set of 7 elements, you can "turn it into" a set of 6 elements by removing one of the elements. So, in how many ways can you remove an element from the set of 7 elements, without making the same 6-element set more than once?

Three sets
6 if order doesn't matter
from the numbers 4567 we can have 24 numbers
There are approx 5.709*10^45 possible sets of numbers that can be made out of the composite numbers in 1 and 200.
There are infinitely many possible answers. For example: 1 + 236 1.1 + 235.9 or 1*237 10*23.7 then there are sets of three and more numbers that make 237.
