The argument list in the declaration and definition of the add() method does not follow the syntax of C++. This is basic C++, by the way, and has nothing to do with Qt.

Set up and debug your code as an ordinary subroutine first, before you try to make a library of it.

Seriously, I’m not being facetious... you’re way ahead of yourself. Write a simple main routine to call your functions, and write your header(s) and implementation file(s) as part of the same project. Get that to compile and run correctly before you try to figure out how to package it into a library.

You have some “beginner” errors there, and there’s just way too much extraneous stuff (ARTHEMTICOPRATIONSHARED_EXPORT everywhere, whether it belongs or not) going on for a beginner.
