definition of null vector,

3. The attempt at a solution

null vector : ## |0 \rangle = (0,0,0) ##

inverse of (a,b,c) = ( - a, -b, -c)

vector sum of the two vectors of the same form e.g. (c,d,1) + ( e,f,1) = ( c+e, d+f, 2) does not have the same form. So, the vectors of the form ( a,b,1) do not form a vector space.

Is this correct?
