Hello everyone! I'm new here. I'm starting a self-study of more rigorous mathematics. My background is I have a B.S. in Mathematics(class of '14) and have had rigorous classes but they were, in my opinion, sub-par and not taught as rigorously as they should have been. Truth be told, I probably wouldn't have done that great if they were lol. With that being said, I do have good exposure to calculus as far as computation(integration, differential, Differential Equations). Had a class on "proofs" but never really "got it" as deeply as I'd hoped. With that being said I am self studying and am starting with these two books: https://www.amazon.com/Concise-Introd...9443632&sr=1-2 https://www.amazon.com/Elements-Real-.../dp/013897067X Does anyone have any advice on the sequence of courses I should study after these two books? Should I study Spivak Calculus after Martin Liebeck's book on proofs or go straight to Gaskill's Real analysis?
