In summary, Q.E.D. stands for the Latin phrase "quod erat demonstrandum," which translates to "which was to be demonstrated." It is typically used at the end of mathematical proofs to indicate that the desired conclusion has been successfully proven. Q.E.D. serves as a signal to the reader that the proof is complete and the argument is sound. This phrase has been used since ancient times and continues to be a common way to conclude mathematical proofs.
