I never studied maths or any math-heavy discipline formally (my background is in philosophy), but recently I completed the entire Khan Academy math curriculum. Speaking purely from personal experience, the most valuable math I learned was just basic algebra I had studied in high school but never really mastered. Besides that, I’d say statistics, linear algebra, and parts of calculus (especially series) have been the most useful so far.
Brian Tomasik’s great article on education matters for altruism has a section listing useful disciplines and areas. Within maths, it mentions “probability, real analysis, abstract algebra, and general ‘mathematical sophistication’” (statistics is also listed, but as a separate discipline).
