> The sum of all 90 numbers is < 2^89

Why? (Obviously you wouldn't compute it so what's the "trick"?)

[SilasX → noobie]

The sum of 90 numbers in this context is considered to be easy (esp relative to finding the sum of many possible subsets).

[vog → SilasX]

That's true. However, it is also easy to estimate that sum rather than calculating it exactly, so I adjusted my proof accordingly.
