It’s not differential equations, but it’s certainly math.
My dude, I have a bachelors in Finance and Accounting. I'm fully aware of what it takes to get the degree.
Yes you take some math courses. At most up to Calculus 2. The brunt of your courses are going to be more concentrated in economics and other business oriented courses. That doesn't mean it is a STEM degree. Finance and Accounting are business degrees, that's why every university has it in their business school.
