Not true. I was taught Saxon math - pure long division, multiplication, etcetera - but I can figure out how much change to give a clerk to get quarters back. And unlike too many math victims, I can figure out what my change should be.
It's an excellent math curriculum. Very comprehensive and inclusive.
Did you know that the folks at Saxon, years past, offered to GIVE textbooks to California schools? The CA schools refused the offer. I remember reading where a teacher thought the Saxon curriculum was "too right wing".
Kudos! You are good at math, and this is excellent.
