Possibly metaphysical naturalism is wrong and supernatural things exist! And maybe thoughts (and/or the experience of consciousness) are among those supernatural things. That could be it. In which case sure, maybe solving math problems can create consciousness (why not?).

You are attacking a strawman without answering the question.

Do I think supernatural things like thoughts not being represented in physical reality exist? I defer to Russell's Teapot on this one and lean toward "no". If they do, then attempting to reason about anything gets pretty iffy anyway. Who knows what might exist or be true, in that case!

[Eisenstein]

There is nothing that says that if thoughts are not made in brains they must be supernatural. You are making conclusions not based on evidence or argument.
