Linear algebra, statistics (lots of it), numerical methods (good for simulations and solving diffeqs), game theory (my personal favourite)

You can use mathematics/statistics for anything, but it doesn't mean that the statistics themselves are objectively sourced or measured, or that any conclusions can be derived from them.

If you can do linear regression you'll be fine. Nonlinear regression and you'll be the one-eyed Anon among the blind.

Not science. and desu, economics is boring as fuck

Ancient dudes were struggling to find mice numbers to justify intelligent design
You can't call that science

>>11129406
economy is far from just being numbers
read keynes’ general theory of employment, interest and money, thats the base to every other relevant book there is

That depends on what you're interested in because subfields of economics vary in their mathematical sophistication. If you're good with differential equations, then you should be able to coast along undergrad economics. If you're not used to "abstract" math, then maybe you'll have to put in more effort to understand mathematical economics. Economics textbooks usually teach you everything you need to know to follow the material, or at the very least make it clear where you need to look. For starters, you could acquaint yourself with the discipline by reading introductory material. Some classics include Mas-Colell et al.'s Microeconomic Theory (microeconomics), Economic Growth (macroeconomics), Krugman et al.'s International Economics & International Finance (international trade and finance), Gibbon's Game Theory for Applied Economists (game theory), and Wooldridge's Introductory Econometrics (econometrics). I don't know of any good introductory books in mathematical economics though, so you might need to learn this one on your own unless someone else can give you specific suggestions.

Cocaine taxes, to understand countability of this subject.

What are your obligations to learn economics?

Linear Algebra and Functional Analysis, mostly over Hilbert spaces.
Real Analysis and differential equations, both ordinary and partial, in particular qualitative analysis and properties of solutions.
Probability theory, specially Markov series and Hidden Markov models, plus stochastic calculus with stochastic pdes.
Statistics, in particular, time series, robust methods and large sample theory. Econometrics as well.
Convex analysis.
Fixed point theory, at least the basic theorems, i.e. Brouwer`s, Banach`s, etc.
Game theory, extensively and in depth. That`s your bread and butter.
Dynamical systems.
Numerical methods for everything above.

I`d recommend picking up Lax`s functional analysis and Zeidler`s four course on Nonlinear Functional Analysis, excluding the one about mathematical physics. Shirayev is good for probability, while Hayashi for econometrics. I don`t have any particular recs for the remainder.

Keynes was great, but stop being autistic about muh numbers.

Do you have the opportunity to take university classes in Economics or are you just looking for some books to introduce you to general economics? I'm in my last year of an Economics major/Math minor and I would say if you've taken all of calculus, linear algebra and a couple of statistics classes you should have a solid enough mathematical background to understand the undergrad level of Econ.

As some other posters have pointed out, though, Economics is not only about math but is also about reasoning through the decision making process of people. To understand Economics in its academic context is to understand the formalization of the decisions individuals make about how to use their resources under conditions of scarcity. If this is what you're after, then you should just get a microeconomics textbook. Similarly to Math, it's hard to point you in a particular direction to understand the whole of it, but once you have the basics down you can read a lot more broadly.
