A strong background in mathematics is helpful even if you're not directly solving mathematical problems. A legal argument is not unlike a geometry proof. You start with certain facts (like geometry postulates), you use legal precedents (like geometry theorems), and you connect them using logic.

Many companies use sophisticated data analysis (statistics) to determine what products to produce and sell and how to price them. Even if you're not the one doing this analysis, an understanding of how that works can help you make smart business decisions.

And even if your career never requires you to solve an equation or write a proof, every career will require you to solve challenging problems. And math is all about solving challenging problems. The persistence and thinking skills you learn in math will help you solve any challenging problem.
