How many numbers can be expressed as the sum of two or more distinct elements of the set {0,1,2,3,4,...,16}?
+2666 The smallest number that can be expressed is 1(0,1).
The largest number that can be expressed is 136(0,1,2,3,4,...,16)
Note that because we have a 1 and 2, every number will be reachable between 1 and 136.
Can you take it from here?
