Again with all due respect to Focardi, if he was advanced in illness enough to have trouble with commas and periods in simple math in 2011, how far back can you go to a point where his faculties would be likely fully healthy?
Focardi never failed at public math....even on video. Rossi did as shown above...miserably. Are you confusing Rossi with Focardi? Big difference BTW, as you must know.
