Math books be like this. Stared at this a long time before I realized it was just basically saying that the product of a matrix with its inverse is the identity. Lol why

@mandlebro I've been doing math my whole life. I'm halve decent, invented some stuff, learned some really advanced concepts. But the way math is worded has always been the biggest thing that holds me back. I spend more time trying to figure out what they are saying than actually learning concepts (which is usually easy by comparison.
@freemo @mandlebro I would suggest the writer's talent is with numbers and concepts, not clearly with words.
Sadly, as someone who wants to communicate his thoughts, and specially on a teaching text, should do better.
I remember a dreadful Calculus book, by Moise, which I hated, absolutely.
@mandlebro @freemo Ah, thank you for the clarification! 😉
@design_RG @freemo I should comment that this is not book that is meant to be read by anyone other than mathematicians. Its an AMS monograph on a modern theory that started being developed, I think, in the 80's, namely information geometry. It's also, as far as I know, the first text on the topic. This line was just laughably convoluted for what he was trying to say.
