putting two and two together

Inferring the obvious

Putting two and two together is figuring something out by combining available evidence or clues.

The phrase suggests basic reasoning—if you can add two and two, you can reach an obvious conclusion: When she saw the lipstick on his collar and smelled perfume, she put two and two together.

Sometimes used with the implication that the conclusion, though logical, might be wrong.
