Where'd a person find why quantums don't work at large scale, using with basic math or simple analogies?

What do you mean why quantums don't work at large scales? I don't know what you're asking.
 
I think he is asking if and why QM breaks down at large scales. It doesn't break down at large scales its effects are just not as dramatic as it would be at smaller scales.

I think I've read, in the press, that there is some type of problem with QM and there is another type of problem with general relativity. Is there an intrinsic difficulty with QM, maybe when dealing with gravity; or is it just that QM isn't as useful on large scales?
 
there is a problem of combining general relativity and quantum mechanics as a single theory
