Sep 10, 2019 at 21:39 comment added user3395 I don't think it's specifically defined anywhere because it's just a personification, and the usual definition applies (whether what's being personified is male or not is not really important here, although maybe it'd be a little odd to say she to reference one such guy).
Sep 10, 2019 at 21:26 comment added Jyrki Lahtonen This is correct. And I agree with @urnonav. When I was in grad school in the US in the late 80s, "guy" could refer to a mathematical object of many different kinds, not just a number, an element of many kinds of a set. A particularly vivid memory to me personally involves the first question in my candidacy exam (aka quals), when I referred to an element of a group as "what about this guy?" (pointing at a dot on the chalkboard) at a critical point.

Sep 10, 2019 at 20:41 comment added Bavyan Yaldo You are right. i haven’t seen it in a written form. However, i hear this very often from native English speakers in math in university. I hear this from KHAN Academy in Youtube videos of math explanations as well. @urnonav
Sep 10, 2019 at 20:37 comment added urnonav Could you provide an example sentence? English speakers will refer to almost anything - tangible or intangible - as "guy", including algebraic expressions. This is widely done but is not very formal.
