Math's degrees are so underrated and everyone gives it shit. But from what I've seen at university degrees that rely heavily on mathematics such as engineering, actuarial studies and mathematics degrees are the most practical and highly sought after. It's pretty much because of the problem solving skills you gain throughout the degree.This is way better than any rote learning commerce kid out there.
With a maths degree you can work pretty much everywhere. There are like separate divisions in investment banks for scientists, engineers and mathematicians. They're even more important now considering the world we live in. Technology and BIG DATA dominates and a maths degree in statistics would get you places. Maths is pretty much another unique language that not many people understand and those that do understand it are very valuable.
If you're interested look up Optiver. They're a trading company and they pretty much hire maths graduates to make them the big $$$. There's a guy his name is Sen Lin (James Ruse) he has an adv maths degree of UNSW and came first for both MX1 and MX2. Works as a banker/trader at optiver.
Google loves science and maths kids. Anthony Morris (
http://www.science.unsw.edu.au/current-students/wavelength/2013/july/alumni) is another one of these smarties. Did advanced maths majoring in pure mathematics. He has a job working at google. Pure mathematics and coding/computers don't seem really compatible right? Well not really the problem solving skilsl from maths is so highly sought after that these firms will eat these kids up.
So yeah just providing a new perspective on things. IF YOU REALLY MUST DO COMMERCE/BUSINESS maybe try the commerce/science(adv maths) degree. I shit you not some of the most gifted people do mathematics.
