How many numbers can be expressed as the sum of two or more distinct elements of the set \( \{ 0, 1, 2, 4, 8, 16 \}?\)

There are six numbers in the set but we don't count the empty set so 2^6-1=63 numbers

The numbers 1-31 with the exceptions of the ones in the set (0,1,2, 4, 8, and 16). 0 isn't in the first set (1-31)

31-5=26 numbers.
