Currently deciding on what to study. I'm really interested

>mathematics
>marxian economics
pick one

If you're in the US give UMass Amherst a look. I went to school there and studied economics. I'm not a Marxist but we had the leading Marxian program on earth I think (citation needed).
Wolff used to teach there before he died and a lot of his disciples still teach there.

why do you want to study something that doesn't work?

Study economics in general, even if you want to focus on Marxist, so that you don't just cocoon yourself in an academic bubble. Departments are full of people who think they have the world figured out, but don't talk to the people on the next floor.

Marx is literally the most important economist to have ever existed, doesn't mean he is right.

Economist here, can say that if you will actually decide to study serious economics (as in, math based, non-heterodox), you'll realize on your own that Marxian economics is full of crap.

Even as a socialist, I feel the need to say it's totally wrong to call Marx an economist.

He was a philosopher, who made some really lastingly important criticisms of capitalism and tried to predict what would come after it. Communism is basically a vision the world post-economics.

Calling economics "mathematics based" is kind of misleading. Idealized markets do have some nice mathematical properties that you can use to make predictions. But no one has ever lived in an ideal market, because the perfect rational agents they're based on don't exist. Economics is mostly a social science, like sociology for people who like money.
