In mathematics, QED stands for the Latin phrase “Quod Erat Demonstrandum,” which translates to “that which was to be demonstrated.” It is used to indicate the completion of a proof, meaning that the statement that was being proved is now accepted as true. In other words, it is a way to signify that the proof is complete and that the statement is true.

QED is often used at the end of a proof, after all of the steps of the proof have been completed. It is also used to indicate that the proof is valid, and that the statement being proved is true. In some cases, it may be used to indicate the conclusion of an argument or a discussion.

The use of QED dates back to the ancient Greeks, who used it to signify that a statement had been proved. It has since become a standard way to indicate the end of a proof, and it is used in many different areas of mathematics. It is also used in logic, philosophy, and computer science.

QED is an important part of mathematics, as it is used to signify that a proof is complete and that the statement being proved is true. Without QED, it would be difficult to know when a proof is finished and when it is valid. As such, it is an important part of mathematical proofs and arguments.
