It would be nice if there was some text written to explain the mathematical formula above.
That is one of my main complaint to students whose homework solutions are a bunch of math without text or explanation (other than the self-explanatory algebra and the presumed conventions for symbols).
You should mark it 0, with no explanation.
Yes, I could do that. Then again: the first time they should only get a warning unless I really can’t parse it out at all.
Make give them two scores – mechanics (M), and a conceptual score (S). Final score (FS) FS = M * S
“were” writing…
