I ask "Does one need a master's in math before taking a PhD in pure math?" (And then applied to the US for this question)
Chris C's answer suggests that in the US, I may just go straight from a bachelor's in mathematics to a PhD in mathematics, but I don't quite have a bachelor's in mathematics. My bachelor's is in mathematical finance.
Edit: Sorry. I forgot to emphasize something. My bachelor's didn't have a thesis. I had a thesis in master's, but it was in mathematical finance. Will this be a problem? I was thinking math PhD programs in the US think students have some background in mathematical research.
"A variety of areas throughout mathematics. And that answer of mine that you link was written for an audience completely unfamiliar with mathematical research - someone ready to pursue a PhD should already know what it says. – Nate Eldredge Apr 2 at 13:33"
