lol. Math is commerce (really, it's dealing with money, numbers, problems :p)
Although it may seem 'ridiculous' that methods is a pre-requisite (25), i'm surprised that it's not higher [sorry costargh

]. The major studies in commerce are (excluding actuarial lol): Accounting, Finance, Economics, Marketing, and Management. I'm telling you now that every single major study has math, just not as hard as others.
The ranking will go according to this (of course, excluding actuarial lol)
1. Finance
2. Economics
3. Accounting
4. Marketing
5. Management
In detail, I can tell specific calculations you may need to be equipped with for the above.
1. finance - Knowledge of various models (black-scholes), able to read and correctly interpret graphs, able to solve financial mathematics problems (SCIENTIFIC calculators ONLY allowed, no graphics)
2. economics - Econometrics. Derivation of graphs, elasticity, curves and many more.
3. accounting - NPV (net present value), time value of money, forensic accounting methods
4. marketing - Statistics, data mining and others (but i vaguely know about marketing)
5. management - Productivity calculations. (verrry simple though, simple x/y, management is piss easy lol)
So there is reasons why unis across the world require math. Trust me, you
must repeat it, just think about, it's just another 10 months of real trouble, heartache and aguish and then you can relax. It's
certainly worth it

3. and 4 are interchangable actually lol.
