What does it mean?
The phrase "It doesn't add up" means that something is illogical or inconsistent; the facts or details do not make sense when considered together.
Tone
Informal and conversational, often expressing doubt or skepticism.
Origin
The phrase originates from mathematics, where numbers must align to logically fit a solution. When they don’t, the result is invalid, and this concept has been metaphorically applied to situations involving logic or reasoning.
Examples of usage
