I'm something of a newcomer to this topic. By Saxon Math, do you mean math from the Anglo-Saxon era, or math materials by Saxon Publishing?
(please don't laugh if I seem clueless)
Yes, it is the math from Saxon Publishers. It is very no frills and very thoroughly explains everything. You can basically teach yourself math using it. My kids did and came to me when they didn't understand something and I finally learned all that math that I didn't get in high school.
Funny thing is, the school district we used to homeschool in was so impressed with the home schoolers standardized test math scores and noticed that most of them used Saxon Math, so they looked into it and started using it themselves. Their math scores went up, too.
