TITLE: Is calculation a part or just a result of Mathematics?
QUESTION [12 upvotes]: There is a question that came to my mind that I'd like to discuss here. I hope it is clear what I want to express since English is not my mother tongue.
Since I have started studying mathematics and physics there is one thing I have noticed especially in comparison to the math-courses I've attended in Gymnasium (High School equivalent). It is the lack of calculations. And by calculation I mean things like $2+2$, $\int_a^b dx (f(x)) $
Whereas in physics I have moments where I need a calculator, in maths the closest thing I've come to that is by looking for a derivative. And  since I have been attending mathematics I have encountered a rather interesting view on the relation between calculation and maths by asking other mathematicians what they think of that.
It is a view that sees calculation as an offspring or even just a byproduct of mathematical work. A view that claims that mathematics just examines, defines and checks. It is somehow like a searching for new things within its boundaries. In case of simple arithmetic operations in $\mathbb{R}$ that would mean that the real mathematics lies in the pure construction of the logic behind. Same for those math text problems everyone knows from High-School.  
But is this perception really reasonable or just too extreme?
I would argue that indeed it is too extreme. One may even need simple calculations for examining new theories, proving or disproving them the most evident example being to find a counterexample.  
But what if one adds the assumption that mathematics only uses calculations as a means to an end? That would not exclude all practical calculation from mathematics but most done for example in High-School or financial mathematics, physics etc. Solving those math text problems in High School would not really be mathematics then. It somehow would be like the relationship between physics and engineering.
So what do you think?  
Thank you very much and every answer is appreciated,

REPLY [2 votes]: Calculations are a tool that mathematicians employ to determine what is true.
Let me back up. What is mathematics really? Anything which you can precisely axiomatize and reason about falls within the domain of mathematics. Doing mathematics is reasoning about these axioms and their consequences. Thus you can view chess as mathematics, or any result of physics which proceeds from some set of assumptions (or laws) to a conclusion merely by means of logical argument. (Not everyone agrees with this view of course).
Calculations, as I say, are tools which help with this process. But they are also conclusions themselves since they follow from the axioms. We only prove such things once and then use the result as a shortcut thereafter, but doing so does not remove them from the realm of mathematics. 
In some sense, all ends in mathematics are means to other ends. There is no question which mathematicians want to settle exclusively for its own sake. There are always more questions that follow; we always want to know what forthcoming results portend, and in some cases make contingent arguments in anticipation of those results. 
A good analogy might be the following: children practice spelling, vocabulary and grammar in school. New words may come into existence, new spelling conventions, and even new grammatical structures (over longer periods of time). All of this is part of language, but is concerned with developing the fundamental tools required to understand language and even make new linguistic innovations. It represents the goals of fluency and comprehension, and is the means to mastery and communication.
