  Borderline surprised this is on the frontpage. :) Here are two comments from yours truly on what "ideals" are and why they make sense to think about for number theory: https://news.ycombinator.com/item?id=14016396 https://news.ycombinator.com/item?id=14016396 https://news.ycombinator.com/item?id=14017178 https://news.ycombinator.com/item?id=14017178

    Ah yes, but it is the generalisation to _fractional_ ideals that is required to obtain the ideal class group.

      I know, but it's good to understand the _trivial_ fractional ideals first. :) (I like your blog, btw!)

        Thanks for the kind remarks :-)
