Cách sử dụng
The expression "cancel out" means that something is nullified or made ineffective. It is often used in math, where two numbers or variables can "cancel out" each other when they are multiplied or divided. For example, if we have the equation 5x + 10 = 20, we can "cancel out" the 10 by subtracting it from both sides of the equation, leaving us with 5x = 10. In this case, the 10 and the -10 "cancel out" each other.In everyday language, we might also use the expression to describe how one action or event can make another one irrelevant or meaningless. For example, if you planned to go to a party but then got sick, your illness might "cancel out" your plans to go.
