David Chess talks about his daughter's science class, asking:
is there any respectable linguistic community for whom "battery"
is a subset of "generator"?
Several things come up: I was leafing through some materials from my childhood, and came across notes from a session on fractions. There, carefully laid out and obviously memorized, were terms that I have never heard as an adult.
And in related news, Alec learned the lesson: He talked to the right people and got a different math teacher, and hasn't called me for tutoring help even when I've offered.

Thought about "reciprocal" a bit: I've heard and read and used "one over" a lot. I've never heard someone talk about, say, in real-time rendering, the difficulties of calculating "the reciprocal of z". This may be an anomaly just because the equations I'm usually working with are either something simple like 1/z or have enough divisions that terms like "reciprocal" aren't precise enough to describe the operation.
But unlike "proper" and "improper" fractions (<1 and >=1, respectively), numerator and denominator get used in my life a lot.

The ones I found again easily this morning were "proper fractions" and "improper fractions".

So what are those terms you've never used as an adult?
Numerator, denominator, reciprocal?

if you're lucky, if you're not a whole bunch of people smarter and
more articulate than you will ridicule you, and we will leave
such ridicule in place.
