But in the US at least, you can get through k-12 without learning basic intro math stuff, like linear algebra or calculus. If that was the minimum, we could, I guess, handle basic applied math like intro differential equations in the first year of a 2-year degree, and then spend the second year figuring out how to ask the computer to solve those problems…
