Question

can you add zero to a null vector?

Answer 1

Hi! If you want to add something to a vector, it has to be a vector with the same number of components!

\(0\) is not a vector.
\(\vec 0\) is the null vector, where all components are \(0\).

So, you cannot add them. Any questions?

Sidenote:
\(0+0=0\)
\(\vec 0+\vec 0=\vec 0\) ... with three components, \(\left<0,0,0\right>+\left<0,0,0\right>=\left<0,0,0\right>\)
