What Is a Zero Sum Game

Today I watched a panel discussion about US China relations in the 21 century. The panelists kept talking about  “ the zero sum game” which I have no idea what this means.

So I googled it. Here is the explanation.

What Is a Zero Sum Game?

The zero sum game is an idea from game theory. It finds most of its application in economics and political theory. In a zero sum game, gains for one person(s) causes losses for another person(s) in an identical amount. The net change for everyone involved is zero and no wealth is created or destroyed during the transaction.

Honestly, I still feel very confused.

Learning english is so hard. I feel very frustrated. Sorry I am writing something very negative here. After all Tomorrow is another day:)
