Talk:Compound interest

To anyone who owns the book "Borrowed Time"

I have listened to the audiobook of this. However, I do not still have access to the account which I used to do so nor do I still have said download (it's a long story). I tried the Google Books preview but it cuts out half the pages of the specific section I'm looking for. So, what I'm asking is, anyone who has the book, preferably physically on paper, could they please write a lede for this article? Because I know that book actually has the Doctor explain what compound interest is, but he uses a metaphor with cake and icing to do so, so we must consider T:NO RW very carefully as to how much we can actually say about what compound interest IS, at least in the DWU. I am aware what it is IRL, of course, but "IRL" explicitly doesn't apply on this wiki. So I need somebody to check how detailed the Doctor's explanation in the actual book is and thus how much we can say here. But at the moment we have no lede whatsoever and that DEFINITELY needs to change at least. NightmareofEden ☎ 12:48, 1 September 2021 (UTC)
