The phrasal verb "cancel out" is primarily used in informal to semi-formal contexts. It commonly appears in conversation and written English to describe situations where one effect negates another, bringing about a neutral result. For example, "The costs and benefits of the project cancel out," indicates that the advantages and disadvantages balance each other. "Cancel out" finds particular usage in mathematical and scientific discussions when describing scenarios such as cancelling terms from both sides of an equation to simplify it. It can also be encountered in everyday speech when discussing life events, decisions, or actions where two opposing factors render the overall outcome ineffective or unchanged. While not typically associated with highly formal or academic writing, "cancel out" is sufficiently versatile to be understood across various contexts and levels of discourse.
