So am I but supposedly at the upper division university level.  One of the more familiar models for Euclidean geometry is the Cartesian plane and, since the axioms are categorical, analytic proof is equivalent to synthetic proof and sometimes easier if not as mathematically pretty, a fact I learned (and used) as a sophomore in high school. Many of the students in my class this quarter (probably the weakest I've ever had) don't have the algebra skills to even solve specific problems with the coefficients rigged to be easy and too many hints given.  How they survived calculus (were given for credit calculus is probably a more appropriate way of putting it) is anybody's guess but the basic problem is not a guess; too many years of educational malfeasance at least at grading time (including my own).

Bob, I'm teaching geometry.


Well, then I guess you can blame the students for not knowing enough algebra to answer your questions.
