After doing nearly all the coursework for a Ph.D. in math, I then did all the coursework for a Ph.D. in statistics and completed that degree.

comment Name and role of a particular finite group?
@TobiasKildetoft : Of course it is $S_3$, but it is also a set of rational functions, and things can be said about rational functions.

comment mathematical proof vs. first-order logic deductions
@DougSpoonwood : I agree that proof-hood is objective; I don't think that conflicts with understanding being "psychological". Principles of epistemology are objective rules whose purpose is to create understanding.

comment highest-common-factor $\cong$ greatest-common-divisor
I think the algebra-precalculus tag ought to be deprecated.

@zhw : I would probably construe the question as meaning a function that is continuous on the domain $\mathbb R/p$, i.e. reals modulo $p$, for some $p>0$. ${}\qquad{}$

comment greatest common divisor of 4 integers
Instead of recalling that gcd is associative, maybe one should suggest that the poster learn that gcd is associative, perhaps by writing a proof.
