Fermat’s Last Theorem is not proved. It is a conjecture. A conjecture is a statement that is made based on evidence, but that has not been proven true or false. In mathematics, a proof is a demonstration that a statement is true. For example, the statement "all prime numbers are odd" is a conjecture. No one has ever proven this statement to be true, but mathematicians have shown that it is likely to be true.
