Little bit of maths+economics vs accounting major

Hi, I've been trolling these forums for a while now. I previously wanted to pursue a career in auditing but, from what I've read on these forums, a career in trading seems more interesting to me. I'm fairly new to the world of finance so I don't know much yet.

I'm currently a uni student in Australia doing a Bachelor of Commerce. And I'm having a bit of trouble deciding what subjects to do. I have decided that I want to major in finance. And with the remaining subjects I have available, I can decide to do a major in accounting or I can use those subjects to study a mixture of economics and maths but with no majors in them (btw: I don't think we have such things as minors at my uni). Basically, I have 8 spare subjects available. To get a major in accounting I need to study 8 subjects. So I can use those 8 on accounting or a mix of maths and economics.

I have read that maths is a plus when applying for jobs in trading but how much of a plus is it compared to a major in accounting?

The maths subject Im listing here has 2 other pre-requisite maths subjects so I cannot just take it on it's own. I need to devote 3 spare subjects to it. The maths subject that I wanted to take and that I felt was useful had this description:

"Mathematical definition of options and other financial derivatives; probability models; mathematical models of random processes; applications; numerical methods; Monte Carlo methods.

Objectives The learning objectives of this unit are to:

* develop an understanding of the modern approach to evaluation of uncertain future payoffs;
* develop an understanding of the <span class='keyword_link'><a href="/resources/skills/trading-investing/arbitrage" target="_blank">concepts of arbitrage</a></span> and fair games and their relevance to finance and insurance;
* develop an understanding of concept of conditional expectation and martingales and their relation to pricing of financial derivatives;
* develop an understanding of the random processes such as Random Walk, Brownian Motion and Diffusions and be able to apply them for modelling real life processes and risk models;
* obtain skills to use Ito's formula ;
* develop the skills to price options by using the Binomial and Black-Scholes models;
* ability to simulate the price process and obtain prices by simulation;
* ability to formulate discrete time Risk Model in Insurance and use it for control of probabilities of ruin."

I am leaning towards the maths subjects and a bit of economics but am pretty clueless. So would this maths subject be much more relevant and useful than an accounting major? I already have some basic knowledge of accounting because I've already taken 2 accounting subjects.

Sorry if this is kind of confusing to read.

Thanks

edit: woops I really shouldve said econometrics instead of maths since the subject is listed under econometrics.
