The rules
Choose ten numbers and compare sums of subsets.
Imagine a game played with the integers from 1 through 100. I choose ten distinct numbers and show them to you.
Your task is to find two distinct subsets of those ten numbers whose sums are equal. For example, two different pairs might both add up to 102. If you find such a pair of subsets, you win.
Who can force a win?
Decide whether the chooser can prevent an equal-sum pair.
I win if I can choose ten numbers for which no two different subsets have the same sum. The puzzle is to determine which player has a winning strategy.
This is a monthly puzzler made with MoMath. The short video poses the question and leaves the solution for a later installment.
