Hello vtile,

{[a,b] [c,d] [e,f]} {[g,h] [i,j] [k,l]} - you get { [a-g,b-h] [c-i,d-j] [e-k,f-l]} But the lists must have same size.

{[a,b] [c,d] [e,f]} {[g,h] [i,j] [k,l]} + you get {[a,b] [c,d] [e,f] [g,h] [i,j] [k,l]}
{[a,b] [c,d] [e,f]} {[g,h] [i,j] [k,l]} ADD you get { [a+g,b+h] [c+i,d+j] [e+k,f+l]}
{[a,b] [c,d] [e,f]} {[g,h] [i,j] [k,l]} DOT you get { a*g+b*h c*i+d*j } and for 3D vectors it works in the same way for CROSS, too.

That's fine, isn't it, and I hope I answered your question,too.

greetings
