# How do you find u+v and u-v given u=<-5,3> and v=<0,0>?

$\vec{u} + \vec{v} = < - 5 , 3 >$

$\vec{u} - \vec{v} = < - 5 , 3 >$

#### Explanation:

$\vec{u} = < - 5 , 3 > \text{ & } \vec{v} = < 0 , 0 >$

$\vec{u} + \vec{v} = < - 5 + 0 , 3 + 0 >$

$\vec{u} + \vec{v} = < - 5 , 3 >$

vecu-vecv=(-5-0,3-0>

$\vec{u} - \vec{v} = < - 5 , 3 >$

this implies that $\text{ "vecv=<0,0>" }$is the additive identity.
