I'm currently interested in and new to QM and I'm reading a book, that teaches QM in an easy way. But there are many mathematical expressions about various things, like the quantum state of a spin when an apparatus is rotated along the x-, y- or z-Axis.
I can think of what the purpose of these expressions might be, but I want to know it more clearly.
What's the purpose of writing these mathematical expressions and do I really have to know/understand every single detail of these expressions or just generally know what they are?
Thank you !
PS: I'm currently not studying physics, but I'm thinking of studying physics in the future. ^^

Mathematics has some very useful properties that make it superior to natural language in describing physical theories:
This makes mathematics an invaluable tool for the physicist, especially in the context of quantum mechanics, where our common intuition fails.
