Question 1149228
.


When I see such posts from @josgarithmetic, I become really sad and angry.


The educational value of such posts is 0 (zero, ZERO).


Moreover, posting such a nonsense, he actually blocks the posts from other tutors (from me, for example), 

from which the reader / (the visitor) could learn something useful.



It is why I say that real contribution of @josgarithmetic is, actually, NEGATIVE at this forum.



Dear visitors, you will continue to get such GIBBERISH from him until YOU APPLAUD him.
