There are some required courses in commerce which requires some understanding of maths, although nothing major.
You'd have to do one statistics course which isn't too hard, there's not much assumed knowledge in it. The later year statistics courses feature more advanced mathematics, but you don't have to do them unless it is a major requirement
There will also be a finance course, which would only require some basic algebra, but the emphasis is more on remembering formulae.
Some higher level economics courses have some higher level maths (econometrics for example)
As for accounting, there are no complex maths involved.
Beyond some mandatory first year courses, which feature easy maths anyway, you can complete a commerce degree without much maths.
