I study pure mathematics and seeing people in this thread misunderstanding what it is is oddly amusing. Protip, we don't just add and substract large numbers or find roots of high degree polynomials. Maths does not end with your high school knowledge.
>If anything it works rather in the opposite way: people who are intelligent in general tend to be better in maths as well.
This is the answer, but maths does help you order and structure your thoughts because you need it for writing proofs. The effect of learning to think in such a way extends to any field that requires reasoning, and not only that, a lot of modern fields are built on maths.
If anyone is interested there is an article that applies mathematics to Bach, it's called "An aspect of harmony in music of Johann Sebastian Bach".
