Not too easy. Not too difficult.
Math is the language of commerce. It will include maintaining Balance sheets ,and that required basic math that deals with huge numbers. It involves economics that has various formulas, that require derivations and integration .So ,you need to be good at calculus to perform.
First let me explain it for commerce. Yes, for commerce sector maths can be useful. But not that tough level of maths as we are thinking. Just basic one like calculating cost, ROI, EPS etc etc. You may argue that to calculate cost you need to know various formulas, take various assumptions etc etc. Dont worry the staff whom you have hired can do it for you. You just need to understand the end meaning. Warren Buffet had said," All you need to know is basics. I never knew when I have used algebra before making Investment" Now let me define in terms of CA For exams not much but if you will to work as risk analyst or Valuation expert etc maths will help you otherwise what you need is I have already mentioned "Simple Math"

Advice for students:
"The advice I would give would be to go to the open days and ask plenty of questions about university life, the course and support services. Chat to students for some honest first-hand experience of studying there. It may seem a hassle if your university is far from home, but the train ticket to visit is cheaper than dropping out after one term."
