    This is a pigeonhole question, not an induction question.

    If you have 10 different numbers, how many different ways can you choose a subset of them? (to make a sum)

    and also,

    what is the range of answers you can possibly get? (numbers chosen from 1-99 and up to a maximum of 10 numbers)
