In Oklahoma, the requirement usually is up to “algebra 2” - this is mostly domain and range, finding roots of polynomials, and logarithms.
IMHO, the world would be better if calculus was a required part of the high school curriculum. Like yeah, most people aren’t going to need the product rule in day to day life, but the fundamental ideas about rates of change seem like they’re something that everyone human deserves to be exposed to.


I’ve never used anything beyond basic algebra and basic geometry outside of a classroom. I have used statistics but I don’t remember that being taught in high school, maybe that should change.
Anything beyond those should be optional but definitely made available for those who are interested.
I say there should be more emphasis on the practical applications of the more basic math.
Too many people barely understand interest rates on car and home loans and can’t figure out what they can actually afford. More high level math isn’t going to help them deal with every day issues involving math.
