<p>^Yeah, I should probably mention that my post was more oriented towards the pure math side of things. Linear algebra and real/complex analysis are important for any type of math major, but abstract algebra and topology are much more on the “pure” side. In addition, differential equations would definitely be a core class for an applied math degree.</p>
<p>If you decide to do any type of math major, though, I don’t think it’s a good idea to wait to learn how to write proofs. While getting skilled at and comfortable with proofs takes time and practice, learning the basics of how to write them is pretty trivial. If you’re thinking about a math degree and don’t have any experience with proofs, now’s a good time to at least get acquainted with them. In any case, it’ll help you figure out if a math degree is right for you.</p>
