Hi Cassidy, I questioned what accountants did when I was in high school as well. I thought most accountants did taxes, and while some of them do, there are a lot of other categories that fall into the realm of accounting like auditing, advisory, consulting, etc. For example, I am an auditor, so I look at company's financial statements and make sure the numbers included on them are presented materially correct, and like some of the other responses already, there is a lot of writing and documenting that we have to do as well.
It's a common misconception that accounting involves a lot of math. As I described accounting to freshmen when I used to tutor, it's more like learning a new language than it is math. Accounting classes more so involve understanding what causes something to be classified a certain way. Most math accountants typically do is very basic (add, subtract, divide, multiply - that's pretty much it) and excel does all the work there.
The perfect right answer to going to be highly dependent on what kind of accounting your getting into as some areas are going to be more involved than others. Broadly though, I would not classify accounting as in the math field at all, it's more about the classification of transactions than it is about math. There will be some calculations depending on what your working on, but that is not typically where the accountant can add value. Accountants should be able to analyze those classifications in the form of a financial statement and make thoughtful opinions on what they mean to stakeholders. Against popular opinion, accounting is not just about math and often times involved very little.
I think there is much more to it than number crunching...and you will have excel for that anyway.
An important element of the role is networking. You need to interact with every department and they may need your help on a number of subjects.
The numbers can also help for decision making and analysis. If your processes are managed well, you can spend quite a bit of time in looking for what the numbers mean and how you can help the business find the right strategy. This is particularly true of management accounting.
