Zip(Mod(k, 2), k,{0, -2, -5, 1, -2, -4, 0, 4, 12})
does not give the anwser in CAS as in algebraview do
The same problem 
Zip(Mod(k, 2), k,{0, -2, -5, 1, -2, -4, 0, 4, 12})
does not give the anwser in CAS as in algebraview do
I confirm
I think Mod does not work well in CAS with char expressions
That is true, but i do not know whyBut, it works well using CAS for mobile (I tried using my iphone)
Thanks, fixed for next release!
