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.
Budgeting and more probabilities/statistics are where I think it should be.
Both of those directly relate to improving your life.
And fucking Excel. Better yet teach budgeting and spreadsheet courses in one.
If people had stats, budgeting and excel it would be an incredible improvement.
Budgeting also only gets you so far in our dystopian age when you need 2 full time jobs to pay rent.
