In a game spread over four rounds, a player's points change by: round 1 +18, round 2 -25, round 3 +12, round 4 unknown. If the player's total after all four rounds is exactly 0, what must the round-4 change be?

Question

Accepted Answer

-5. First three rounds: 18 + (-25) + 12 = 5. For the total to be 0, round 4 must be -5, since 5 + (-5) = 0.
