How to remove number from "Appendix" in latex

Question

I want to write "Appendix" without a number in the PDF document. But the following code prints the Appendix with a number (e.g. 5 Appendix)

\section{Appendix}

Is there any way to remove the number from Appendix?

Answer 1

Add a star (*) after the section, and it will remove the number from Appendix.

Change from

\section{Appendix}

to

\section*{Appendix}
