explain what is the concept of 'zero-sum game'
user
a zero-sum game is a situation where one person’s gain is exactly balanced by the losses of the other players. in other words, the total amount of losses and gains must sum to zero. an example of a zero-sum game is a game of chess, where the sum of all pieces on the board is always zero.
