Define v as a vector in $K^n$.
Can I write v-v=O and also v-v=0?
Where O is the zero vector and 0 is a scalar.
Can't seem to find this anywhere..

Technically $\vec{v}-\vec{v}$ is the zero vector. The notational distinction is sometimes not made between the zero vector and the zero scalar because $0\vec{v} = \vec{0}$ for any vector $\vec{v}$.
