[refactor] Add a default value to 'parseArithmetic' in the arithmetic example grammar

[iK4tsu]

By adding a default value, there's no longer the need to have an overloaded function. Since the function never modifies the original AA, there's no need for it to be passed by reference either.

Thanks a lot!

I'll have to create one. Do you have a preferred color?

Not really, can be whatever you prefer. Thank you! :smile:

You can add hacktoberfest tag on the repo, so you don't need to add this label on every PR :)

I have looked for that option, but I'm just a maintainer, and I think you have to be owner for that.
