# Vector plus vector equals scalar ? (Nabla operator)

A quick question that is currently bothering me.

I have the following equation:

$\mathbf{E}+\frac{\partial \mathbf{A}}{\partial t} = -\nabla V$

My question is, how can the right side, being a vector, ever become a scalar ?

Or am I missing something fundamental here ? (The equation is from my Electrodynamics book)

$E_x + \frac{\partial A_x}{\partial t} = -\frac{\partial V}{\partial x}$
$E_y + \frac{\partial A_y}{\partial t} = -\frac{\partial V}{\partial y}$
$E_z + \frac{\partial A_z}{\partial t} = -\frac{\partial V}{\partial z}$
