ok why is it called different. is there more maths involved in one or another
Because different institutions like to call the same things by different names.
For example some University's call subjects courses, some call courses subjects. It's like the pronunciation of tomato. to-mato or tom-ato. Same dice.
If you want to know the exact differences between degrees (at different universities), check out the suggested study plans for the different degrees side by side.
But for the point of calling a degree B.Commerce or B.Business, in terms of naming it's the same thing.
