I'm now retired and would like to learn about number theory purely for my own enjoyment. I have a knowledge of pure mathematics that I would guess is up to about first year undergraduate level but I'm very rusty on it.
I want to ask a question about which route(s) to take in order to further my progress. I have some ideas already about how to proceed. For example, I could take the historical route via the ancients through Fermat or I could ignore history altogether and just focus on those aspects of number theory that are most relevant today, e.g. complex analysis and group theory etc.
I'm not asking for an answer here to the above - my query on Meta is whether my question can be formulated in a way that is suitable for Stack Exchange or whether I should seek a different forum.
