A mathematical proof is like a story that uses numbers and symbols to show that something is true. It's like a game of detective, where we use clues to show that something is true. There are different kinds of proofs, but all of them use symbols and numbers to explain why something must be true. Some proofs might need diagrams and drawings, too, to help explain things. In the end, when all the clues are put together correctly, it will show that what we were trying to prove is true.
