Zero is a number (a scalar quantity without unit) while zero vector (or null vector) is a vector quantity having zero magnitude and arbitrary direction.
no,zero cannot be added to a null vector because zero is scalar but null vector is a vector,although null vector has zero magnitude but it has direction due to which it is called a vector.
The null vector, also called the zero vector, is a vector a, such that a+b=b for any vector b. Also, b+( -b)=a An example in R3 is the vector <0,0,0> Here are some examples of its use <2,2,2>+<-2,-2,-2>=<0,0,0> <2,2,2>+<0,0,0>=<2,2,2>
there is none you weasel. the only good matrix is revolutions. :)
The zero magnitude by itself is no big deal. A greater problem is that no definite direction can be assigned to it. However, like many other mathematical structures, a zero element is required for the theory to be complete.
