I would say our concept of "zero" and "one" has been far from static through time and no all ethnicities share precisely the same meanings.
My ethnicity is informed by abstract algebra such that any element playing the role of "identity" vis-a-vis an operation we call "multiplication" is a good candidate for the name "one". Like when functions compose via the multiplication operator, such that f(g(x)) == (f * g)(x), then the identity function would be our "one" (Python4, Lesson1, Project 1). Composable(lambda x: x) would be "one" in this algebra of composing functions.
Having abstract algebra colors my "one" (imparts a spin) that I wouldn't necessarily have if I got my "one" just from Sesame Street and US-published CS-unfriendly algebra texts, which are far less sophisticated. We call it "algebra" but don't teach about identity elements with respect to addition and multiplication very effectively.
All the group theory tends to come *after* calculus in the ambient idiocracy (milieu) which is ass-backwards and symptomatic of math-teaching's backwardness, a leading cause of declining living standards, per my belief system / attitude / bias.
