Why is there a difference in physics in general, and the physics in quantum mechanics, or is there any? From my understanding, it's a difference of forces, but does the math not work out the same?

Classical physics cannot describe quantum physics- but quantum physics can replicate classical. The main reason we don't use quantum physics in the classical realm is because it's far too mathematically challenging for large systems.

This Q&A might be helpful for a better understanding.

No. The math doesn't work out the same. You can use Classical Physics to explain things like Feynman Diagrams and you can't use QM to explain the universe at a large scale.
