than geometry: but you can't always get what you want.
Cold-reading a geometry book is useful. Doing the same for an algebra book is that, and sometimes also fun.
Also: I left today after getting to a lesson whose beginning falls into "This isn't right. This isn't even wrong." A sentence in a high-school math review/test prep book that begins "If lines are congruent," has nowhere useful to go. I'm hoping that in the morning I will be able to get some idea of what the writer actually meant to say and/or what the editor thought was there, which may mean guessing at the line that the compositor dropped. If not, it gets flagged as "Rosemary, this doesn't make any sense. What's in the manuscript?"

Why do they still make new geometry books? I don't think I've ever seen one that wasn't an eerily faithful translation of The Elements. I don't want to say that the field hasn't changed since 300 BCE, but um ... has it?
