The expression "put two and two together" means to use clues or evidence to figure out something that is not directly stated or obvious. It's like solving a puzzle by combining different clues to find the answer. For example, if someone is always tired and has dark circles under their eyes, you might "put two and two together" and think they are not getting enough sleep. It's a way of saying that you have figured something out by using your reasoning skills.
