The expression "trade off" means when you have to give up something to get something else you want. For example, if you want to buy a new video game, but you don't have enough money, you may have to trade off spending money on something else to save up for the game. It's important to make good trade-offs, where you give up something that's not as important, to get something you want or need more.
