The Reason It Works

The idiom "add up" is a commonly used phrase in English that means something is logical or makes sense. It conveys the idea that different parts or elements fit together to form a cohesive whole. This idiom can be traced back to mathematics, where adding numbers together to find a sum or total was the basis of the concept. Over time, it extended metaphorically to other areas of life, signifying a logical progression or coherence.

The idiom "add up" finds application in various contexts, including detective stories and financial or mathematical calculations. In a detective story, if the clues "add up," it means they are consistent and point to a likely solution or explanation. Conversely, if the clues do not "add up," there may be missing or contradictory information that needs consideration. Similarly, in financial or mathematical calculations, if the numbers "add up," it signifies that the totals and calculations are correct and balanced. If the numbers do not "add up," errors or discrepancies need resolution.

In addition to concrete scenarios, the idiom "add up" can also be used more abstractly. It can describe someone's behavior or statements as either "adding up" or not. If someone's behavior or statements "add up," it means they are consistent with their character or previous actions. If their behavior or statements do not "add up," it suggests inconsistencies or contradictions.
