That's an interesting point of view: in a way he "doesn't know me anymore", so why would he trust me? And he has to trust me because if he doesn't understand why I am better in this specific topic (maths), then the only thing left is his belief...

I once heard flat-earthers in a train. One was saying "It's like school, e.g. physics: they purposely make it such that we don't understand it to confuse us. Because we're not worse than anybody else, so we should understand, right? If nobody understands, that's because they bullshit us!". I really wanted to say "counter-example: I could understand physics at school :-)".
